Toward the end of the episode, Beale mentions that the Commodore 64 is the most popular personal computer of all time. This is true. At over 17 million units sold it ranks as #1, beating the next highest selling PC, the NEC PC-98xx series by about 2 million units. Interestingly, neither company is still in the home computer business. NEC has shifted their focus to corporate computers and Commodore went out of business in 1994.
