Isn't HD TV broadcast?
I dont think broadcast television will go away....I think it will get better. With the digital signals, they can pack 5 channels where one now exists.
What is to prevent the NFL, or Nascar, in the future from including DTV rights in their future negotiations. Lets say NBC wants to get back in to the NFL, and bid on a package to show 2 NFL games at the same time. (NBC.1 and NBC.2) with them getting a certain number of commercial time to sell within the broadcast.
Cable is getting too expensive...our area just went to $70.00 for analog, extended basic service.
"Broadcast" as defined as something sent out to a wide audience of disparate interests. This goes back to when there was only so much frequency spectrum. The networks tried to appeal to the wide audience. Hence, sports, comedy, drama, etc. The downside is that they had a near monopoly and their "newscasts" turned into opinion pieces sold as "news."
But once cable came along and now broadband web service, the constraints are no longer. Just as their "newscasts" are challenged, the need for their programming that appealed to the wide audience is no longer needed...
