The Apple II was the first "mass-market" personal computer. Based around a 6502 processor and up to 64k of RAM, it was one of the first computers to offer built-in color graphics on a TV. Thanks largely to applications like VisiCalc and later&AppleWorks, it and it's progeny continued to sell well up until the early 1990s, at which point John Sculley finally killed the line after years of no advertising.
