Don't deny it: you love TV. In case you've forgotten how much, take a peek at this clip from a 1975 Sony promotional video for the very first Betamax, the LV-1901 (apparently, it came with the system). It will remind you how home video recording not only freed us from "the restrictions of time" but from houseguests that wouldn't leave—and allowed us to one-up our tennis partners. And listen to the sorrow in the voices of the couple at the end who discuss how they just don't make shows like that anymore. Mannix, we hardly knew ye.
