I seriously doubt it with 40% of sations going with the original deadline.
Postponing the deadline likely delayed a mini-stimulus as well. If you're wanted people to spend money, this would have been one way to nudge them along. I imagine electronics retailers would have seen at least a little spike in sales.
TV is about ads. Believe it or not, there are people out there that still don't get the TV conversion. My mother-in-law still can't run the VCR. Thing is, these are also the majority people that call in and buy stuff from the informercials and are most affected by the Pharmaceutical commercials. It's not about people feeling sorry for someone or caring weather or not they get to catch their re-runs of Golden Girls. It's people making sure their ad dollars are going some where.
Also, sometimes it's not about being lazy or stupid. Some people just don't care. I don't. Really I don't. If my TV stopped working tomorrow (It would kill my wife) but it wouldn't really bother me at all. I can usually watch what I need to on the internet, if it's sports, I'd go to a bar. Which is where I usually have to go any ways to see the games I want to watch.
Believe me, the only reason for the delay is they are afraid of losing ad revenue. Which is in tight demand right now.
