I understand the general argument, and I don't disagree in general. My intuition is that showing 50 inch TVs to someone who just bought one is not ideal [0]. My point is that the specific examples provided (Hollywood blockbusters, etc.) are not accompanied by any evidence or reasoning to convince me that these industries are not doing a good job of satisfying the market.

[0] That said, I've seen lots of counterintuitive but very real phenomena regarding user behavior, so I won't claim to be that confident about this being ineffective. Perhaps people return TVs a lot and buy other ones. I don't have the data.

The data might just show that offering 50 inch TVs to someone who just bought one is actually a rich opportunity. Perhaps both televisions were stolen in a burglary. Or someone is finally upgrading all their televisions from CRT to flat screen -- maybe they moved from a house to a small apartment. It would not surprise me in the least if people were 10 times more likely to purchase a television having just bought one, compared to individuals randomly selected.
