The personal computer industry's first two decades unfold through the machines that built it: the Altair 8800 kit that started home computing as a hobbyist's project, the Apple I and Apple II that turned it into a business, and VisiCalc, the spreadsheet program that gave ordinary people a reason to buy one. The film tracks how IBM's entry with the PC legitimized the whole category for corporate America, then follows Apple's Macintosh push to unseat IBM's dominance through the mid-1980s and into the 1990s. Interviews with the engineers, executives, and early hackers who lived through these launches sit alongside archival footage of the products themselves, tracing the rivalries and licensing decisions that decided which companies survived. The story ends at the release of Windows 95, the moment Microsoft's operating system became the default interface for home computing just as the Dot-com boom was beginning. Bear markets, garage startups, and boardroom bets recur throughout as the industry moves from hobbyist curiosity to a business worth fighting over.
