I watch only one half-hour of TV per week--THE SIMPSONS--so I am not really qualified to assert this. Maybe a reader can clarify. Are there such things nowadays as TV ads for ice cream? I think not. In the 1950s, Americans had to be trained to consume luxuries like ice cream. Now we eat it automatically, three times a day! So why waste money on ads?
Cartrivision was the first VCR marketed to the American public, back in the early 1970s. It predated VHS and Betamax. However, it soon failed, for a variety of reasons. First, it was sold as a TV/home entertainment center/movie camera combo, which made it very expensive. That is, you couldn't buy just the player alone and attach it to your existing set. You had to buy the whole bundle. Second, you could rent movies for it, but you couldn't rewind the movies, so you could only watch them once. This limitation was designed into it at the insistence of the movie industry. Finally, perhaps its slightly creepy ads played a role in its demise. Maybe it's just me, but I definitely sense a pervy vibe coming off of the dad in the scene below.
