Star Wars came first, by 8 years. The first film opened in 32 American cinemas.

Side by side

Star Wars

Star Wars opened in May 1977 on fewer than forty screens because the distributor had little faith in it, and it went on to be the highest-grossing film made to that point. Fox let Lucas keep the merchandising and sequel rights in exchange for a lower directing fee, a decision that transferred an extraordinary amount of money. It is eleven years younger than Star Trek.

Windows

Windows 1.0 shipped in November 1985, twenty-two months after the Macintosh, and it was not an operating system — it was a graphical shell running on top of MS-DOS, and remained so until Windows NT in 1993 and the consumer transition with Windows XP in 2001. Version 1.0 could not even overlap windows: they tiled, because Apple's legal position on overlapping windows was unresolved.
