According to Gartner, the following is the worldwide device shipments (referring to wholesale) by operating system, which includes smartphones, tablets, laptops and PCs together.

Shipments (to stores) do not necessarily translate to sales to consumers, therefore suggesting the numbers indicate popularity and/or usage could be misleading. Not only do smartphones sell in higher numbers than PCs, but also a lot more by dollar value, with the gap only projected to widen, to well over double.{{Cite news|url=https://www.gartner.com/en/newsroom/press-releases/2017-04-06-gartner-says-worldwide-end-user-spending-on-devices-will-grow-2-percent-in-2017-while-unit-shipments-remain-flat|title=Gartner Says Worldwide End-User Spending on Devices Will Grow 2 Percent in 2017, While Unit Shipments Remain Flat|access-date=2017-12-07|language=en}}

On 27 January 2016, Paul Thurrott summarized the operating system market, the day after Apple announced "one billion devices":

{{blockquote|Apple's "active installed base" is now one billion devices. [..] Granted, some of those Apple devices were probably sold into the marketplace years ago. But that 1 billion figure can and should be compared to the numbers Microsoft touts for Windows 10 (200 million, most recently) or Windows more generally (1.5 billion active users, a number that hasn’t moved, magically, in years), and that Google touts for Android (over 1.4 billion, as of September).

My understanding of iOS is that the user base was previously thought to be around 800 million strong, and when you factor out Macs and other non-iOS Apple devices, that's probably about right. But as you can see, there are three big personal computing platforms.|source=Paul Thurrott{{cite news |title=Apple's active installed base is now over 1 billion strong |url=https://www.thurrott.com/mobile/ios/64193/apples-active-installed-base-in-now-over-1-billion-strong |first=Paul |last=Thurrott |newspaper=Thurrott.com |date=27 January 2016 |quote=there are three big personal computing platforms.

For 2015 (and earlier), Gartner reports for "the year, worldwide PC shipments declined for the fourth consecutive year, which started in 2012 with the launch of tablets" with an 8% decline in PC sales for 2015 (not including cumulative decline in sales over the previous years).{{cite press release|url=https://www.gartner.com/newsroom/id/3185224 |title=Gartner Says Worldwide PC Shipments Declined 8.3 Percent in Fourth Quarter of 2015: Holiday Sales Provided Little Cheer to PC Vendors in 2015 |date=12 January 2016 |access-date=15 March 2016}}

In May 2020, Gartner predicted further decline in all market segments for 2020 due to COVID-19, predicting a decline of 13.6% for all devices. while the "Work from Home Trend Saved PC Market from Collapse", with only a decline of 10.5% predicted for PCs. However, in the end, according to Gartner, PC shipments grew 10.7% in the fourth quarter of 2020 and reached 275 million units in 2020, a 4.8% increase from 2019 and the highest growth in ten years." Apple in 4th place for PCs had the largest growth in shipments for a company in Q4 of 31.3%, while "the fourth quarter of 2020 was another remarkable period of growth for Chromebooks, with shipments increasing around 200% year over year to reach 11.7 million units. In 2020, Chromebook shipments increased over 80% to total nearly 30 million units, largely due to demand from the North American education market." Chromebooks sold more (30 million) than Apple's Macs worldwide (22.5 million) in pandemic year 2020.{{Cite web |title=Gartner Says Worldwide PC Shipments Grew 10.7% in Fourth Quarter of 2020 and 4.8% for the Year |url=https://www.gartner.com/en/newsroom/press-releases/2021-01-11-gartner-says-worldwide-pc-shipments-grew-10-point-7-percent-in-the-fourth-quarter-of-2020-and-4-point-8-percent-for-the-year |access-date=2021-03-03 |website=Gartner |language=en}}

According to Gartner, worldwide PC shipments declined by 16.2% in 2022, the largest annual decrease since the mid-1990s, due to geopolitical, economic, and supply chain challenges. {{cite news |title=Gartner Says Worldwide PC Shipments Declined 28.5% in Fourth Quarter of 2022 and 16.2% for the Year |url=https://www.gartner.com/en/newsroom/press-releases/2023-01-11-gartner-says-worldwide-pc-shipments-declined-28-percent-in-fourth-quarter-of-2022-and-16-percent-for-the-year#:~:text=For%20the%20year%2C%20PC%20shipments,a%2016.2%25%20decrease%20from%202021. |access-date=29 December 2023 |work=Gartner |language=en}}

In 2015, eMarketer estimated at the beginning of the year that the tablet installed base would hit one billion{{cite web|url=http://www.emarketer.com/Article/Tablet-Users-Surpass-1-Billion-Worldwide-2015/1011806|title=Tablet Users to Surpass 1 Billion Worldwide in 2015 - eMarketer|work=emarketer.com|access-date=22 March 2017}} for the first time (with China's use at 328 million, which Google Play doesn't serve or track, and the United States's use second at 156 million). At the end of the year, because of cheap tablets{{snd}} not counted by all analysts{{snd}} that goal was met (even excluding cumulative sales of previous years) as:

{{blockquote|Sales quintupled to an expected 1 billion units worldwide this year, from 216 million units in 2014, according to projections from the Envisioneering Group.

While that number is far higher than the 200-plus million units globally projected by research firms IDC, Gartner and Forrester, Envisioneering analyst Richard Doherty says the rival estimates miss all the cheap Asian knockoff tablets that have been churning off assembly lines.[..]

Forrester says its definition of tablets "is relatively narrow" while IDC says it includes some tablets by Amazon — but not all.[..]

The top tech purchase of the year continued to be the smartphone, with an expected 1.5 billion sold worldwide, according to projections from researcher IDC. Last year saw some 1.2 billion sold.[..]

Computers didn’t fare as well, despite the introduction of Microsoft's latest software upgrade, Windows 10, and the expected but not realized bump it would provide for consumers looking to skip the upgrade and just get a new computer instead.

Some 281 million PCs were expected to be sold, according to IDC, down from 308 million in 2014. Folks tend to be happy with the older computers and keep them for longer, as more of our daily computing activities have moved to the smartphone.[..]

While Windows 10 got good reviews from tech critics, only 11% of the 1-billion-plus Windows user base opted to do the upgrade, according to Microsoft. This suggests Microsoft has a ways to go before the software gets "hit" status. Apple's new operating system El Capitan has been downloaded by 25% of Apple's user base, according to Apple.

This conflicts with statistics from IDC that say the tablet market contracted by 10% in 2015 with only Huawei, ranked fifth, with big gains, more than doubling their share; for fourth quarter 2015, the five biggest vendors were the same except that Amazon Fire tablets ranked third worldwide, new on the list, enabled by its not quite tripling of market share to 7.9%, with its Fire OS Android-derivative.{{cite web|url=https://www.androidheadlines.com/2016/02/idc-tablet-shipments-decline-fifth-straight-quarter.html|title=IDC: Tablet Shipments Decline For Fifth Straight Quarter - Androidheadlines.com|date=1 February 2016|work=androidheadlines.com|access-date=22 March 2017}}

By late 2016, Android had been said to be "killing" Apple's iOS market share (i.e. its declining sales of smartphones, not just relatively but also by number of units, when the whole market was increasing).{{Cite web |last=Parrack |first=Dave |date=2016-08-18 |title=Android Is Killing iOS, Uber Launches Self-Driving Cars...

That point decline means an 11.6% relative decline (from 14.6% down to 12.9%).

Although by units sold Apple was declining in the late 2010s, the company was almost the only vendor making any profit in the smartphone sector from hardware sales alone. In Q3 2016 for example, they captured 103.6% of the market profits.{{cite news |last=Patrick |first=Seitz |date=3 November 2016 |title=Apple iPhone Grabs 104% Of Smartphone Industry Profit In Q3 |newspaper=Investor's Business Daily |url=http://www.investors.com/news/technology/click/apple-iphone-grabs-104-of-smartphone-industry-profit-in-q3/}}

Considering all personal computers, Microsoft Windows is well below 50% usage share on every continent, and at 30% in the US (24% single-day low) and in many countries lower, e.g. China, and in India at 19% (12% some days) and Windows' lowest share globally was 29% in May 2022 (25% some days), and 29% in the US.{{Cite web|title=Operating System Market Share South America|url=https://gs.statcounter.com/os-market-share/all/south-america/#weekly-202013-202019|access-date=2020-10-01|website=StatCounter Global Stats|language=en}}

For a short time, iOS was slightly more popular than Windows in the US, but this is no longer the case. Worldwide, Android holds 45.49%, more than Windows at 25.35%, and iOS third at 18.26%.

Windows is still the dominant desktop OS, but the dominance varies by region and it has gradually lost market share to other desktop operating systems (not just to mobile) with the slide very noticeable in the US, where macOS usage has more than quadrupled from Jan. 2009 to Dec. 2020 to 30.62% (i.e. in Christmas month; and 34.72% in April 2020 in the middle of COVID-19, and iOS was more popular overall that year;{{Cite web|title=Operating System Market Share United States Of America|url=https://gs.statcounter.com/os-market-share/all/united-states-of-america/#monthly-202001-202012-bar|access-date=2021-01-05|website=StatCounter Global Stats|language=en}} globally Windows lost to Android that year,{{Cite web|title=Operating System Market Share Worldwide|url=https://gs.statcounter.com/os-market-share#monthly-202001-202012-bar|access-date=2021-01-05|website=StatCounter Global Stats|language=en}} as for the two years prior), with Windows down to 61.136% and ChromeOS at 5.46%, plus traditional Linux at 1.73%.{{Cite web|title=Desktop Operating System Market Share United States Of America|url=https://gs.statcounter.com/os-market-share/desktop/united-states-of-america/#monthly-200901-202012|access-date=2021-01-05|website=StatCounter Global Stats|language=en}}

There is little openly published information on the device shipments of desktop and laptop computers. Gartner publishes estimates, but the way the estimates are calculated is not openly published. Another source of market share of various operating systems is StatCounterhttps://gs.statcounter.com/#desktop-os-ww-monthly-201508-201508-bar StatCounter basing its estimate on web use (although this may not be very accurate). Also, sales may overstate usage. Most computers are sold with a pre-installed operating system, with some users replacing that OS with a different one due to personal preference, or installing another OS alongside it and using both. Conversely, sales underestimate usage by not counting unauthorized copies. For example, in 2009, approximately 80% of software sold in China consisted of illegitimate copies.{{cite news| url=https://www.nytimes.com/2009/10/19/business/global/19iht-windows.html|title=Software Pirates in China Beat Microsoft to the Punch | work=The New York Times | date=19 October 2009}} In 2007, the statistics from an automated update of IE7 for registered Windows computers differed with the observed web browser share, leading one writer to estimate that 25–35% of all Windows XP installations were unlicensed.{{cite web|url=http://www.seopher.com/articles/around_25_35_of_windows_xp_systems_are_pirated_calculations_included_|title=Around 25–35% of Windows XP systems are pirated (calculations included)|archive-url=https://web.archive.org/web/20160304063513/http://www.seopher.com/articles/around_25_35_of_windows_xp_systems_are_pirated_calculations_included_|archive-date=2016-03-04}}

The usage share of Microsoft's (then latest operating system version) Windows 10 has slowly increased since July/August 2016, reaching around 27.15% (of all Windows versions, not all desktop or all operating systems) in December 2016.

In recent years, Linux has gained more interest among gamers than ever before, especially thanks to projects like Wine and Proton. Wine allows Windows programs to run on Linux, while Valve's Proton makes many games on Steam directly playable without any additional configuration. The Linux version of Steam and devices such as Steam Deck using Linux-based SteamOS have made Linux more accessible as a gaming platform. The number of Steam games currently available on Linux exceeds the total number of games available on XBOX, Nintendo Switch and PlayStation platforms{{cite web|access-date=June 3, 2025 |archive-date=June 2, 2025 |archive-url=https://web.archive.org/web/20250602225803/https://www.protondb.com/ |publisher=ProtonDB |title=Data from Valve's proton project site. |url=https://www.protondb.com/}}.

Internet based servers' market share can be measured with statistical surveys of publicly accessible servers, such as web servers, mail servers{{cite web|url=http://www.securityspace.com/s_survey/data/man.201007/mxsurvey.html|title=Mail Server Survey|publisher=Security Space|date=August 2011}} or DNS servers on the Internet: the operating systems powering such servers are found by inspecting raw response messages. This method gives insight only into market share of operating systems that are publicly accessible on the Internet.

There will be differences in the result depending on how the sample is done and observations weighted. Usually the surveys are not based on a random sample of all IP addresses, domain names, hosts or organisations, but on servers found by some other method.{{citation needed|date=December 2011}} Additionally, many domains and IP addresses may be served by one host and some domains may be served by several hosts or by one host with several IP addresses.

;Note: Revenue comparisons often include "operating system software, other bundled software"{{cite web |url=https://www.idc.com/getdoc.jsp?containerId=prUS24476413 |publisher=International Data Corporation |title=Worldwide Server Market Revenues Decline −3.7% in the Third Quarter as Weak Unix Server Demand Weights on the Market, According to IDC |access-date=24 February 2014 |archive-date=8 February 2014 |archive-url=https://web.archive.org/web/20140208235052/http://www.idc.com/getdoc.jsp?containerId=prUS24476413 |url-status=dead }} and are not appropriate for usage comparison as the Linux operating system costs nothing (including "other bundled software"), except if optionally using commercial distributions such as Red Hat Enterprise Linux (in that case, cost of software for all software bundled with hardware has to be known for all operating systems involved, and subtracted). In cases where no-cost Linux is used, such comparisons underestimate Linux server popularity and overestimate other proprietary operating systems such as Unix and Windows.

Mainframes are larger and more powerful than most servers, but not supercomputers. They are used to process large sets of data, for example enterprise resource planning or credit card transactions.

The most common operating system for mainframes is IBM's z/OS.{{Cite web |title=What is z/OS? |url=https://www.techtarget.com/searchdatacenter/definition/z-OS |access-date=2024-02-15 |website=Data Center |language=en}}{{citation needed|date=August 2016}} Operating systems for IBM Z generation hardware include IBM's proprietary z/OS,{{cite web|url=http://www.ccianet.org/index.asp?sid=5&artid=62&evtflg=False|title=IBM Tightens Stranglehold Over Mainframe Market; Gets Hit with Antitrust Complaint in Europe|publisher=Computer & Communications Industry Association|archive-url=https://web.archive.org/web/20100706133546/http://www.ccianet.org/index.asp?sid=5&artid=62&evtflg=False|date=2 July 2008|archive-date=6 July 2010|access-date=27 May 2015}} Linux on IBM Z, z/TPF, z/VSE and z/VM.

Gartner reported on 23 December 2008 that Linux on System z was used on approximately 28% of the "customer z base" and that they expected this to increase to over 50% in the following five years.{{cite web |url=http://mediaproducts.gartner.com/reprints/novell/vol3/article1/article1.html |title=Vendor Rating: Novell, 2008 |work=Gartner RAS Core Research Note G00162399 |date=23 December 2008 |access-date = 23 November 2009}}{{dead link|date=December 2021|bot=medic}}{{cbignore|bot=medic}} Of Linux on IBM Z, Red Hat and Micro Focus compete to sell RHEL and SLES respectively:

Like today's trend of mobile devices from personal computers, in 1984 for the first time estimated sales of desktop computers ($11.6 billion) exceeded mainframe computers ($11.4 billion). IBM received the vast majority of mainframe revenue.{{Cite news |last=Sanger |first=David E. |url=https://www.nytimes.com/1984/02/05/business/bailing-out-of-the-mainframe-industry.html |title=Bailing Out of the Mainframe Industry |date=1984-02-05 |work=The New York Times |access-date=2020-03-02 |page=Section 3, Page 1 |language=en-US |issn=0362-4331}}

From 1991 to 1996, AT&T Corporation briefly owned NCR, one of the major original mainframe producers. During the same period, companies found that servers based on microcomputer designs could be deployed at a fraction of the acquisition price and offer local users much greater control over their own systems given the IT policies and practices at that time. Terminals used for interacting with mainframe systems were gradually replaced by personal computers. Consequently, demand plummeted and new mainframe installations were restricted mainly to financial services and government. In the early 1990s, there was a rough consensus among industry analysts that the mainframe was a dying market as mainframe platforms were increasingly replaced by personal computer networks.{{cite news|last=Also|first=Stewart|title=IBM still has brains to be player in client/server platforms|url=https://books.google.com/books?id=XTwEAAAAMBAJ&q=death+mainframe&pg=PA4|access-date=Dec 26, 2013|newspaper=InfoWorld|date=Mar 8, 1993}}

In 2012, NASA powered down its last mainframe, an IBM System z9.{{cite book|last=Cureton|first=Linda|url=https://blogs.nasa.gov/NASA-CIO-Blog/2012/02/12/post_1329017818806/|title=The End of the Mainframe Era at NASA|publisher=NASA|date=11 February 2012|access-date=31 January 2014}} However, IBM's successor to the z9, the z10, led a New York Times reporter to state four years earlier that "mainframe technology—hardware, software and services—remains a large and lucrative business for IBM, and mainframes are still the back-office engines behind the world's financial markets and much of global commerce".{{cite news |last=Lohr |first=Steve |title=Why Old Technologies Are Still Kicking |url=https://www.nytimes.com/2008/03/23/technology/23digi.html |access-date=Dec 25, 2013 |newspaper=The New York Times |date=March 23, 2008}} {{As of|2010}}, while mainframe technology represented less than 3% of IBM's revenues, it "continue[d] to play an outsized role in Big Blue's results".{{cite news|last=Ante|first=Spencer E.|title=IBM Calculates New Mainframes Into Its Future Sales Growth|url=https://online.wsj.com/news/articles/SB10001424052748703954804575381482738207168|access-date=Dec 25, 2013|newspaper=The Wall Street Journal|date=July 22, 2010}}

The TOP500 project lists and ranks the 500 fastest supercomputers for which benchmark results are submitted. Since the early 1990s, the field of supercomputers has been dominated by Unix or Unix-like operating systems, and starting in 2017, every top 500 fastest supercomputer uses Linux as its supercomputer operating system.

The last supercomputer to rank #1 while using an operating system other than Linux was ASCI White, which ran AIX. It held the title from November 2000 to November 2001,{{cite web|url=https://www.top500.org/resources/top-systems/asci-white-lawrence-livermore-national-laboratory/|title=No. 1 system from November 2000 to November 2001|publisher=top500.org|access-date=22 May 2019}} and was decommissioned in 2006. Then in June 2017, two AIX computers held rank 493 and 494,{{cite web | url = https://www.techfae.com/linux-running-almost-supercomputers/ | title = Linux is Running on Almost all of the Supercomputers | publisher = TechFAE| date = 25 June 2017 }} the last non-Linux systems before they dropped off the list.

Historically all kinds of Unix operating systems dominated, and in the end ultimately Linux remains.
