Intel, a large corporation, was not "enough" for the x86, and so others such as Advanced Micro Devices and Cyrix were needed.

Both the much-disputed Iraq reconstruction no-bid contracts and those awarded after Hurricane Katrina contained "cost-plus" provisions which "guarantee contractors a certain profit regardless of how much they ultimately spend", according to the Wall Street Journal. Critics claim that such agreements "remove any incentives for private companies to control expenses, which are paid for by the tax-payer".[http://tiger.towson.edu/~apeak1/writtenwork/thoughtpieces/radicalsforcapitalismareviewofareview.html Thought pieces: who pays]
A no-bid contract is a military or government contract that is made directly with a corporation, bypassing the standard process of bidding. These contracts can be made much more quickly than a typical contract, however they are often fraught with suspicion. After the 2003 war in Iraq, the Halliburton company, previously headed by then vice-president Dick Cheney, was issued a $2 billion no-bid contract for fuel distribution. Speed is usually the rationale for such contracts.
Just days after Hurricane Katrina, in September, 2005, the Bush administration awarded no-bid reconstruction contracts to companies such as Fluor Corp., Bechtel, Shaw Group, CH2M Hill Cos, and Halliburton's Kellogg, Brown and Root.http://www.washingtonpost.com/ac2/wp-dyn/A55220-2003Aug27?language=printer {{Dead link|date=June 2022}}{{Cite magazine|url=http://www.wired.com/politics/law/news/2005/09/68829|title=Bush Cronies to Mop up Katrina|magazine=Wired}}
History
Although it was recently defined, multisourcing has been practiced in the market since competitors started to produce alternatives to IBM's datacenter products in the late 1980's.Louis V. Gerstner, Jr. Who Says Elephants Can't Dance? Inside IBM's Historic Turnaround. Collins (November 12, 2002). pp. 76 Firms like Gartner and Forrester Research[http://www.forrester.com/Research/Document/Excerpt/0,7211,42569,00.html Outsourcing Providers Need A Strategy Rethink To Address Buyers' Shift To Multisourcing] pushed the term into the public eye.
Future
Multisourcing's strength, first recognized by Gartner Group in 2005, is to continue providing disciplined services via a blend from internal and external sources.{{cite book

The outputs of these workshops are operational level agreements (OLAs){{Cite web|url = http://www.information-age.com/it-management/outsourcing-and-supplier-management/123457348/how-to-make-multi-sourcing-work
