I've been on about podcasting since its inception. Up next: download TV.
Podcasting rocketed into the world since virtually everyone has the equipment needed (a computer and a microphone) to create an audio show. Combine that with the delivery mechanism that the web and RSS give you, and voila.
Seems like we have everything we need readily available to roll our own TV shows, too, and get them in the same way. BitTorrent has provided a wonderful delivery mechanism for the larger video files. In the past few weeks, I've heard of several start-ups being formed to provide such programming. And a few days ago, systm.org released its first show. It's for a geek audience, to be sure, as it's all about making your own warspy scanner. But it's coming.
Think about it. Wouldn't you like to have a TV channel that only shows programs that you're interested in? Wouldn't you like "a la carte" cable? What about folks who want to make programs that are only of interest to a select few people, (especially if you're one of the few)? (Sure, they may not make much money, but if the only cost is time, energy, and love of subject matter, that'd be okay too.)
Heck, if it takes off, I may actually start watching TV again. (Or not...)
