TV is facing the Internet challenge. Ever since the switch to digital broadcast wiped out many folks TV reception, viewers have been turning to the Internet to watch programs. For instance at my place we used to get 8 over-the-air channels. After the switchover to digital broadcasting we only get one. Lotta people who don't have or cannot afford cable don't get to see much TV anymore. At my daughter's place in DC they don't have TV anymore. They have three reasonable modern but non functional TV sets piled up in the dining room to form a modern object d'art.
Enter the Internet. Hulu.com has been offering streaming TV right to your computer. Hulu is a joint venture between NBC, News Corp, and Disney and offers TV programs. Hulu is free (right now anyway) but the owners are conflicted over the Hulu business model. In plain English, they cannot figure out how to make money giving stuff away free. Competitor Netflix charges $8 a month for roughly the same thing.
One unsolved problem, at least in my house, is how to get the Internet TV signal onto the living room TV. The main (desktop) computer is some distance from the TV and running a video cable across two rooms under the rugs is un inviting. I could put a wireless card into backup (laptop) computer) and set the laptop down close to the TV. My newer TV accepts VGA (computer monitor) video. Many (but not all)laptops will output regular composite video (standard analog TV signal like a VCR outputs) if your TV is a little older.
Another unsolved problem is internet bandwidth. There isn't that much of it. If you think the Internet is slow now, wait til everyone is watching TV over the 'net. The "net neutrality" scuffle is an attempt by Hulu and Netflix to force the ISP's not to put their streaming TV on the back burner. The ISP's, given a choice between delaying a website from painting, a matter of a few dozen packets, and delaying some of the 4 million packets for a movie, are going to paint the web site first and do the movie later.
Internet TV may force the ISP's to change their billing practices. Right now broadband is billed at one flat monthly rate. The ISP's find that a small percentage of their customers are hogging most of the bandwidth. To make the bandwidth hogs pay their fair share, the ISP's may have to bill by the byte. The more you download the higher your bill. Hulu and Netflix are against that idea.
