Before the launch of the IBM 5150 Personal Computer in August 1981, personal computers were primarily used by hobbyists with limited applications for the average consumer. The IBM 5150 changed this by enabling users to connect to televisions, process text, and play games, thus transforming business operations and fueling the software industry. The vision of William Lowe, who aimed to make computing affordable for small businesses and everyday users, led to the creation of the IBM PC. Under Don Estridge's leadership, the team utilized off-the-shelf components, including Intel's 8088 microprocessor and Microsoft's MS-DOS, to expedite production. Launched at the Waldorf Hotel in New York with a base price of $1,565, the IBM 5150 quickly gained popularity, leading to the development of hundreds of compatible software programs and hardware products. This open architecture approach set industry standards and made 'IBM compatible' a benchmark in computing. Although IBM's market share declined over time, the legacy of the IBM 5150 remains significant as it laid the groundwork for the modern personal computer industry.
