Prodigy (online service)

The roots of Prodigy date to 1980 when broadcaster CBS and telecommunications firm AT&T Corporation formed a joint venture named Venture One in Fair Lawn, New Jersey.{{cite magazine |magazine=InfoWorld |date=September 13, 1982 |page=6 |title=CBS Venture One videotex market test |url=https://books.google.com/books?id=EDAEAAAAMBAJ}} The company conducted a market test of 100 homes in Ridgewood, New Jerseyand 100 in Fair Lawn, NJ: {{cite book |title=On the Way to the Web: The Secret History of the Internet

After concluding the market test, CBS and AT&T took the data and went their separate ways in pursuit of developing and profiting from this market demand.

Prodigy was founded on February 13, 1984 as Trintex, a joint venture including CBS, computer manufacturer IBM and retailer Sears, Roebuck and Company.{{cite news |newspaper=Computerworld |date=May 21, 1984 |page=113 |url=https://books.google.com/books?id=KAUpSdv4AO4C |title=Trintex CBS-IBM-Sears videotex venture}}Tom Shea, [https://books.google.com/books?id=li4EAAAAMBAJ&pg=PA13 Big firms team up on videotex project], InfoWorld, March 12, 1984 The company was headed by Theodore Papes, a career IBM executive, until his retirement in 1992. CBS left the venture in 1986{{cite web |url=http://www.fundinguniverse.com/company-histories/prodigy-communications-corporation-history |title=Prodigy Communications Corporation History|website=FundingUniverse.com|access-date=July 17, 2021}} when CBS CEO Tom Wyman was divesting properties outside of CBS's core broadcasting business. The company's service was launched regionally in 1988 in Atlanta, Hartford and San Francisco under the name Prodigy. The marketing rollout plan closely followed IBM's Systems Network Architecture (SNA) network backbone. A nationwide launch developed by ad agency J. Walter Thompson and sister company JWT Direct followed on September 6, 1990.

Subscribers using personal computers initially accessed the Prodigy service over copper wire telephone "POTS" service or X.25 dialup. Prodigy employed 1,200 bit/s modem connections for its initial rollout and offered low-cost 2,400 bit/s internal modems to subscribers at a discount to provide faster service and stabilize the diverse modem market. The host systems used were regionally distributed IBM Series/1 minicomputers managed by central IBM mainframes located in Yorktown Heights, New York.{{cite journal |last=Crockett |first=Barton |date=22 October 1990 |title=Distributed network pays off for Prodigy |url=https://books.google.com/books?id=ThAEAAAAMBAJ&pg=PA19 |journal=Network World |publisher=IDG Network World Inc |page=19,22 |issn=0887-7661}}

Thanks to an aggressive media marketing campaign, bundling with various consumer-oriented computers such as IBM's PS/1 and PS/2 as well as various clones and Hayes modems, the Prodigy service soon had more than one million subscribers. To handle the traffic, Prodigy built a national network of POP (points of presence) sites that made local access numbers available for most homes in the U.S. This significantly expanded the service because subscribers were not required to dial long distance to access the service. The subscribers paid only for the local call (usually free), while Prodigy paid for the connection to its national data center in Yorktown.[https://www.theatlantic.com/technology/archive/2014/07/where-online-services-go-when-they-die/374099/ Atlantic magazine: "Rebuilding Prodigy" July 12, 2014]

Under the guidance of Henry Heilbrunn,{{cite news |newspaper=The New York Times |url=https://www.nytimes.com/1991/10/24/us/computer-concern-assailed-on-anti-semitic-notes.html |title=Computer Concern |author=Barnaby J. Feder |date=October 24, 1991}} Prodigy developed a fully staffed 24/7 newsroom with editors, writers and graphic artists intent on building the world's first true online medium. The initial result was that Prodigy pioneered the concept of an online content portal—a single site offering news, weather, sports, communication with other members and shopping for goods and services such as groceries, general merchandise, brokerage services and airline reservations. The service provided several lifestyle features, including popular syndicated columnists, Zagat restaurant surveys, Consumer Reports articles and test reports, games for children and adults, in-depth original features called "Timely Topics", bulletin boards moderated by subject matter experts, movie reviews and email. Working with Heilbrunn in the early stages of Prodigy's design, Bob Bedard pioneered the business model for electronic commerce. Prodigy was the service that launched ESPN's online presence.{{cite news |newspaper=The New York Times |url=https://www.nytimes.com/1993/11/08/business/at-age-9-prodigy-on-line-reboots.html |title=At Age 9, Prodigy On-Line Reboots |author=Glenn Rifkin |date=November 8, 1993}}

Prodigy quickly implemented application standard code modules loaded from diskette. These modules relied upon real-time tokenized data from Prodigy database servers to drive core Prodigy service functionality on local user PCs. This client-server design worked well; by staging application-specific and reusable common code modules on Prodigy end-user diskettes, millisecond "click-to-available-cursor" response times were achieved that were otherwise unachievable in 1986 over slow 1,200-to-2,400 bit/s modems.

The service was presented using a graphical user interface. The Data Object Architecture wrapped vector and incremental point graphics, encoded as per NAPLPS, along with interpretative programs written in the proprietary languages TBOL (Trintex Basic Object Language) and PAL (Prodigy Application Language). NAPLPS grew out of the Canadian Telidon project, becoming an international standard in 1983 after some extensions were added by AT&T Corporation. NAPLPS enabled the display of colors and graphics supporting electronic advertising, publishing and commerce. The initial emphasis was on DOS and later Microsoft Windows. After that, users could use the Apple Macintosh, but some Prodigy screens were not properly configured to the Mac standard, resulting in wasted space or partial graphics.

Prodigy's initial business model relied more on advertising and online shopping for cash flow than on monthly subscriptions. Subscribers were charged a flat monthly fee that provided unlimited access. Initially, a monthly rate was set for unlimited usage time and 30 personal messages. In addition, subscribers could purchase additional messages. Later, Prodigy divided its service into "Core" and "Plus" sections. Core section usage remained unlimited, but Plus sections were limited by usage time. Subscribers were afforded a monthly allotment of Plus time, but if that time was exceeded, the subscriber would incur additional charges based on usage time. A blue indicator in the bottom-right corner of the screen indicated the subscriber's section.

Prodigy's shopping applications initially underperformed relative to expectations. This was attributed to the company's misperception that online shoppers would pay a premium rather than expect discounts for merchandise and to the product's poor graphics that resulted from the limitations of current technology. Using the early NAPLPS graphic standard, rendering realistic images of products was impossible, presenting great difficulty for online merchants to market products.

Despite these challenges, Prodigy was primarily responsible for helping merchants such as PC Flowers become some of the earliest e-commerce success stories. However, revenue from advertising was limited.

By 1993, Prodigy was developing a network architecture now known as a content delivery network in which the network caches its most frequently accessed content as close as possible to the users. The company sold private versions of it within customers' private corporate networks.{{cite journal |journal=InfoWorld |first=Stewart |last=Alsop |title=IBM's vision may be clearing but realizing its focus is years away |date=November 15, 1993 |url=https://books.google.com/books?id=DDsEAAAAMBAJ&pg=PA5 |access-date=October 3, 2017}}

Two of Prodigy's most popular services were its message boards and email. Because Prodigy's business model depended on rapidly growing advertising and online shopping revenue, email was initially developed primarily to aid shopping. However, it later found much greater usage as a means of general communication between users. The popularity of Prodigy's message boards caused users to remain connected to the service far longer than had been projected. This resulted in escalating expenses that adversely affected the service's cash flow and profitability.

To control costs and raise revenue, in January 1991, Prodigy modified its basic subscriber plans by allowing only 30 free email messages each month, while charging 25 cents for each additional email message, a policy that was later rescinded. In the summer of 1993, it began charging hourly rates for several of its most popular features, including its most popular feature, the message boards. This policy was later rescinded after tens of thousands of members left the service.

The price increases prompted an increase of "underground IDs" by which multiple users would share a single account and manipulate the email service to act as private bulletin boards. This was accomplished by sending emails to intentionally invalid addresses containing the name of the intended recipients. The service would return the emails, which were not billed, and users of the shared account would find the returned messages there. Replies were sent by entering the name of the first sender as the addressee, which would again trigger a return of the message.

Prodigy was slow to adopt features that made its rival AOL appealing, such as anonymous handles and real-time chat.

Eventually, the emergence of the Internet and the World Wide Web threatened to leave Prodigy behind.

In 1994, Prodigy became the first of the early-generation dialup services to offer full access to the World Wide Web and to offer Web page hosting to its members. However, since Prodigy was not an actual Internet service provider, programs that needed an Internet connection, such as Internet Explorer and the Quake multiplayer game, could not be used with the service. Prodigy developed its own web browser, but it compared poorly to other mainstream browsers in terms of features.

In 1995/1996, Prodigy hired Ed Bennett and Will Lansing. From 1995 through 1996, Prodigy unveiled several Internet-related products. It debuted its real-time chat area within the service, similar to AOL's. Access to Usenet newsgroups was made available and Prodigy's first web presence, Astranet, was released shortly afterward. Astranet was to be a web-based news and information service supported partly by advertising. However, the site was considered experimental and incomplete. Another innovation was Skimmer, a market trial ISP service that became the base for Prodigy Internet.

In 1996, with Gregory C. Carr as chair, the company retooled itself as a true Internet service provider, making its main offering Internet access branded as Prodigy Internet. This new service featured personalized web content, news alerts to pagers, and Java chat. At the same time, Prodigy deemphasized its antiquated proprietary interface and editorial content, which were relabeled as Prodigy Classic. Prodigy Classic was discontinued on October 1, 1999 because the aging software was not Y2K compliant. The service had 209,000 members when it was discontinued.{{cite news |url=http://www.informationweek.com/y2k-shuts-down-prodigy-classic/d/d-id/1006720 |title=Y2K Shuts Down Prodigy Classic |work=InformationWeek |date=1999-01-25 |access-date=2016-03-16 }}{{cite web|last1=Edwards|first1=Benj|title=Where Online Services Go When They Die|url=https://www.theatlantic.com/technology/archive/2014/07/where-online-services-go-when-they-die/374099/|website=The Atlantic|access-date=4 September 2016|date=July 12, 2014}}

In 1996, Prodigy was acquired by the former founders of Boston Technology and their new firm International Wireless, with Mexican businessman Carlos Slim Helú, a principal owner of Telmex, as a minority investor. IBM and Sears sold their interests to the group for $200 million. It was estimated that IBM and Sears had invested more than $1 billion in the service since its founding.Lewis, Peter H. [https://www.nytimes.com/1996/05/08/business/sears-ibm-near-a-deal-to-sell-prodigy.html "Sears, I.B.M. Near a Deal To Sell Prodigy"]. The New York Times, May 8, 1996. Accessed November 13, 2007. "A person familiar with the agreement said I.B.M. and Sears had agreed to accept as little as $100 million for Prodigy, in effect writing off more than $1 billion they had invested in the online venture during the last decade."

Prodigy continued to operate as it had previously, while Telmex provided Internet access under the Prodigy brand in Mexico and other parts of Latin America, with some services provided by Prodigy Communications in the US.

Prodigy went public in 1999, trading on the NASDAQ under the symbol PRGY.[https://www.google.com/finance/?cid=663014 PRGY]. Google Finance. Later that year, Prodigy entered a strategic partnership with SBC Communications by which Prodigy would provide Internet services and SBC would provide exclusive sales opportunities and network, particularly DSL, facilities. The strategic partnership also gave SBC a 43% ownership interest in Prodigy.{{cite press release |title=SBC and Prodigy Announce Alliance |publisher=AT&T Inc.|date=November 22, 1999 |url=http://www.att.com/gen/press-room?pid=4800&cdvn=news&newsarticleid=7168&mapcode=corporate |access-date=June 15, 2010 }}

On November 6, 2001, SBC purchased 100% interest in Prodigy and brought it private. On November 14, 2001, SBC and Yahoo! announced the strategic alliance to create the cobranded SBC Yahoo!. Sometime after that, SBC ceased offering new Prodigy accounts, and customers were encouraged to migrate to the SBC Yahoo! product line while maintaining their existing Prodigy email addresses.

Prodigy was also one of the first online services to offer a user-friendly GUI when competing services, such as CompuServe and GEnie, were still text-based. Prodigy used this graphical capability to deploy advertising, expecting it to result in a significant revenue stream.

Prodigy offered online banking, stock trading, advertising and online shopping before the World Wide Web became widely used, but was largely unable to capitalize on these first-mover advantages. Decades later, IBM, which now owns some of the original Prodigy patents, continues to sell licenses for basic ecommerce concepts.{{Cite web|url=https://www.bloomberg.com/news/articles/2018-08-13/ibm-wallops-groupon-with-a-vintage-patent|title=IBM Wallops Groupon With a Vintage Patent|last=Nocera|first=Joe|date=2018-08-13|publisher=Bloomberg}}

Prodigy was a forerunner in caching data on and near users' personal computers to minimize networking and server expenses while improving the experience for users.U.S. Patent 5,594,910

Prodigy's legacy architecture was novel at the time and anticipated much of current web-browser technology. It leveraged the power of the subscriber's PC to maintain the session state, handle the user interface and process applications formed from data and interpretative program objects largely pulled from the network when needed. At a time when distributed objects were handled by RPC equivalents, Prodigy pioneered the concept of returning interpretable, platform-independent objects{{Clarify|date=July 2013}} to the caller for subsequent processing.{{Cite web |url=http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=14&f=G&l=50&co1=AND&d=PTXT&s1=filepp.INNM.&OS=IN/filepp&RS=IN/filepp |title=U.S. Patent 5,347,632 |access-date=2007-11-28 |archive-date=2017-02-08 |archive-url=https://web.archive.org/web/20170208073243/http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=14&f=G&l=50&co1=AND&d=PTXT&s1=filepp.INNM.&OS=IN/filepp&RS=IN/filepp |url-status=dead }} This approach anticipated innovations such as Java applets and JavaScript.{{Cite web |url=http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=7&f=G&l=50&co1=AND&d=PTXT&s1=filepp.INNM.&OS=IN/filepp&RS=IN/filepp |title=U.S. Patent 6,199,100 |access-date=2007-11-28 |archive-date=2013-10-22 |archive-url=https://web.archive.org/web/20131022115439/http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/netahtml/PTO/search-bool.html&r=7&f=G&l=50&co1=AND&d=PTXT&s1=filepp.INNM.&OS=IN/filepp&RS=IN/filepp |url-status=dead }}Riordan, Teresa.

By 1994, Prodigy became a pioneer in selling "dial-up" connections to the World Wide Web and sold hosting services for Web publishers.

Prodigy regularly became the focus of discussions on The Howard Stern Show in the mid-nineties. Numerous shows were devoted to it. In addition, Howard met face-to-face with people he had talked to in Prodigy chat groups under a pseudonym. Howard was the most prominent radio name in America, gaining excellent ratings at the time. So it could only have been a positive for the Prodigy brand.

As the company shifted from its focus on its exclusive "Prodigy Classic" content and started transitioning to "Prodigy Internet" as an ISP in the late 1990s, Prodigy found itself competing with many other lower-priced ISPs, and the price didn't support the value of the Prodigy Internet exclusive content available for members. In a letter to members, Prodigy explained that upgrades to Prodigy Classic to resolve its Y2K issues were just too expensive and that it felt investing in Prodigy Internet was the best long-term strategy, as many of the popular services offered by Prodigy Classic could be found elsewhere. This decision was consistent with what other online service providers (AOL, CompuServe, MSN) were doing at the time. Still, with these providers competing primarily on ease of ISP setup rather than exclusive content, the retention value was lost. Many members found more affordable ways to access the online content and services they were used to.

In 1999 the company, now led by a cadre of ex-MCI executives to turn the brand around, became Prodigy Internet, marketing a full range of services, applications, and content, including dial-up and DSL for consumers and small businesses, instant messaging, e-mail, and communities.

In 2000, with subscriber growth exploding and brand attributes at an all-time high, Prodigy explored several partnership deals, including what would have been an unprecedented three-way merger with Earthlink and Mindspring. Ultimately, SBC bought a 43% interest in the company, and Prodigy became the exclusive provider to SBC's 77 million high-speed Internet customers. More than a year later after the launch of Prodigy Broadband (conceived and led by Chris Spanos), SBC bought controlling interest for $465 million when Prodigy was the fourth-largest Internet service provider behind America Online, Microsoft's MSN, and EarthLink. Prodigy in 2000 was reported to have 3.1 million subscribers, of which 1.3 million were DSL customers.

Attempts by SBC to sell the Prodigy brand became public knowledge on December 9, 2005.{{cite web |last=Olsen |first=Stefanie |title=Prodigy up for sale |publisher=CNet News |date=December 9, 2005 |url=http://news.cnet.com/Prodigy-up-for-sale/2100-1036_3-5989754.html?part=rss&tag=5989754&subj=news |access-date=February 18, 2011}}

In late 2006, SBC purchased AT&T Corporation and re-branded itself as AT&T Inc. As of early 2007, there remained within AT&T's Internet operations a small group of former Prodigy employees located in AT&T's Austin, Texas, and White Plains, New York, facilities. What had started 27 years earlier as an AT&T online experiment had come full circle.

Through 2009, the domain www.prodigy.net redirected to my.att.net, which appeared to be a Yahoo!-based content and search portal mainly linking to other online services.

AT&T stopped serving Prodigy-created webpages in 2011,{{cite web |title=Discontinuation of Prodigy Personal Web Pages (PWP) Support |publisher=AT&T |url=http://pages.prodigy.net/cgi-bin/index.cgi |access-date=March 5, 2011 |archive-url=https://archive.today/20110629064209/http://pages.prodigy.net/cgi-bin/index.cgi |archive-date=June 29, 2011 |url-status=dead }} severing yet another tie with the brand.

In Mexico, Prodigy Internet is the main ISP with an estimated 92% of market share. It is also the leader in WiFi (hotspots) and broadband (DSL) access. The broadband service is called Prodigy Infinitum and is available in speeds of 512 kbit/s, 1024 kbit/s, 2048 kbit/s, 4096 kbit/s and 20480 kbit/s.{{cite web|url=http://www.ostamyy.com/ISPs/Mexico.htm|title=Internet service providers Mexico - Directory|access-date=2010-06-17|archive-date=2010-02-27|archive-url=https://web.archive.org/web/20100227025442/http://www.ostamyy.com/ISPs/Mexico.htm|url-status=dead}} The installation and DSL or fiber optic modem are free and it is no longer necessary to sign a two-year service contract. Prodigy Internet in Mexico is part of Telmex (Teléfonos de México) and its sister company Telnor (Teléfonos del Noroeste).

Jerry Pournelle saw Prodigy demonstrated at the 1988 West Coast Computer Faire. He described the user interface as "pretty grim, simplified to the point of near imbecility ... No mouse support. It was all very slow". While acknowledging the potential for improvement, Pournelle said that "for $119.40 a year I'd rather have my local newspaper and the Wall Street Journal".{{r|pournelle198807}}
