Networks are responding to the change in the demand for media, slow or otherwise. We heard about NBC beginning to offer its newscasts for free over the Internet. Now, NBC and CBS are going to offer TV shows on-demand for around 99 cents. With the success of iTunes video and similar technologies, this is a pretty predictable, and smart, step for these media giants to take. NBC is offering commercial-free episodes of various shows, Comcast is offering some, and CBS is in on it too.

"This is an incredibly exciting evolution for CBS and network television - video on demand is the next frontier for our industry," CBS Chairman Leslie Moonves said...
The specifics for each company and how they will offer it isn't fully known, but basically you're paying to replay an episode - a bit bogus if you've already seen it and can record it, but if you missed it and want to watch it, to some 99 cents is worth it. Television and radio are finding it increasingly difficult to compete with the Internet. I'd say within a few years, all television schedules are per-person - you pick what you want, and that's what's on TV, all day long, just for you. For a price.
