Some examples of the ways TV-style content is changing in the face of the internet:

http://vodo.net/pioneerone - Pioneer One is a sci-fi TV series much like traditional series, except that it's directly supported by viewer donations, and distributed via BitTorrent.

http://www.famicomdojo.tv/ - Famicom Dojo explores the features and history of old Japanese videogame consoles, a good example of "long-tail" content becoming viable.

http://www.youtube.com/show/autotunethenews - Catchy remixes of news and commentary shows on legacy TV. This is what happens when random people can edit and retransmit, instead of just consuming shows.
