If you're really into watching classic TV on the web, like AOL's fare at In2TV, you're going to be thrilled to hear that NBC today unfurled a line-up of oldies-but-goodies to stream on their entertainment sites -- NBC.com, SCIFI.com, ChillerTV.com and SleuthChannel.com. NBC is providing full episodes, people, streaming and waiting to be viewed, beginning this month. It's quite a variety of shows too (including some crossovers from one site to the other). "These are the kinds of titles we get requests for all the time at the network, and now we're able to give our viewers a new way to watch their favorite classic shows and share them with their friends," said Craig Engler, Senior Vice President, SCIFI.com.

One of the saddest changes in the television landscape has been the disappearance of the theme song. They're really not that important to the people who create TV shows now (or the networks who want to get more commercials in). Lost has just a single note as their theme song, ER has changed and shortened their theme song, Jericho has static, and Heroes doesn't have a theme song or credits either.

Luckily, the shows that still have theme songs also have opening credits. Shows like The Office and Dexter all have theme songs and opening credits. They're classic TV openings. Of course, it's nothing like years gone by, where almost all shows had theme song and opening credits. The Onion has picked 22 that they feel fit their shows perfectly. I don't know if that is the same as "best opening sequences," but the choices are interesting, quirky, a little maddening, and they left out a few, as I'm sure you'll agree.
