Wintel (portmanteau of Windows and Intel) is the partnership of Microsoft and Intel producing personal computers (PCs) using Intel x86-compatible processors running Microsoft's Windows operating system.

By the early 1980s, the chaos and incompatibility that was rife in the early microcomputer market had given way to a smaller number of de facto industry standards, including the S-100 bus expansion board, the CP/M operating system, the Apple II home computer, the use of the programming language Microsoft BASIC in read-only memory (ROM), and the 5+14 inch floppy drive storage medium. Firms competed fiercely to control the industry, and innovation in hardware and software was the rule. Microsoft Windows and Intel processors gained ascendance and their ongoing alliance gave them market dominance.

Intel has claimed that this partnership has enabled the two companies to give customers the benefit of "a seemingly unending spiral of falling prices and rising performance". In addition, they claim a "history of innovation" and "a shared vision of flexible computing for the agile business".

In 1981, IBM entered the microcomputer market. The IBM PC was created by a small subdivision of the firm. It was unusual for an IBM product because it was largely sourced from outside component suppliers and was intended to run third-party operating systems and software. IBM published the technical specifications and schematics of the PC, which allowed third-party companies to produce compatible hardware, the so-called open architecture. The IBM PC became one of the most successful computers of all time.

The key feature of the IBM PC was that it had IBM's enormous public respect behind it. It was an accident of history[editorializing] that the IBM PC happened to have an Intel CPU (instead of the technically superior Motorola 68000 that had been tipped for it, or an IBM in-house design), and that it shipped with IBM PC DOS (a licensed version of Microsoft's MS-DOS) rather than the CP/M-86 operating system, but these accidents were to have enormous significance in later years.

Because the IBM PC was an IBM product with the IBM badge, personal computers became respectable. It became easier for a business to justify buying a microcomputer than it had been even a year or two before, and easiest of all to justify buying the IBM Personal Computer.[citation needed] Since the PC architecture was well documented in IBM's manuals, and PC DOS was designed to be similar to the earlier CP/M operating system, the PC soon had thousands of different third-party add-in cards and software packages available. This made the PC the preferred option for many, since the PC supported the hardware and software they needed.

Industry competitors took one of several approaches to the changing market. Some (such as Apple, Amiga, Atari, and Acorn) persevered with their independent and quite different systems. Of those systems, Apple's Mac is the only one remaining on the market. Others (such as Digital, then the world's second-largest computer company, Hewlett-Packard, and Apricot) concentrated on making similar but technically superior models. Other early market leaders (such as Tandy-Radio Shack or Texas Instruments) stayed with outdated architectures and proprietary operating systems for some time before belatedly realizing which way market trends were going and switching to the most successful long-term business strategy, which was to build a machine that duplicated the IBM PC as closely as possible and sell it for a slightly lower price, or with higher performance. Given the very conservative engineering of the early IBM personal computers and their higher than average prices, this was not a terribly difficult task at first, bar only the great technical challenge of crafting a BIOS that duplicated the function of the IBM BIOS exactly but did not infringe on copyrights.

The two early leaders in this last strategy were both start-up companies: Columbia Data Products and Compaq. They were the first to achieve reputations for very close compatibility with the IBM machines, which meant that they could run software written for the IBM machine without recompilation. Before long, IBM had the best-selling personal computer in the world and at least two of the next-best sellers were, for practical purposes, identical.
