Joost, the service which is determined to bring high quality TV streaming to your PC, seems to be having its share of network problems at the moment, resulting in stuttery playback, and problems making appropriate connections. However, with an annoucement this morning through the WSJ, (summarized by PaidContent, as WSJ is behind a paid wall) they better prepare for more traffic, as it may be completing the most important part of its strategy: securing quality content.

Its not hard to see Joost’s potential, as it has a slick interface, and has quite a few social networking elements built in; with the pedigree behind its founders (the chaps behind Skype and Kazaa), plus the kind of buzz its been getting (which I have been shamelessly also contributing to), it looks like its going to be an exciting ride.

One of the biggest beefs I have with Joost, however, is its content. Right now the line up is, at best, what could be referred to as “niche” content. Well, that’s what I would qualify anime, brides-gone-crazy, soccer, and the world’s strongest man competition, anyway. For a full listing of their channels (along with their regional availability), go on and check out the channel line up.

The announcement is summarized by PaidContent, but it looks like CBS is bringing its stable of television shows, including NCIS, CSI, and the Evening News with Katie Couric to a number of partners, from MSN, to AOL, NBC (!), and yes, Joost. I think this is a great coup on Joost’s behalf, first of all, because it gets mentioned in the same breath as other major content distributors, but secondly, because they are bringing mainstream content to its service. Stuff that your grandma and niece might want to watch.

While the details still need to get sorted out, such as the revenue splits and so on, its a fantastic and encouraging step for Joost. Here’s hoping that its the first in many content deals with major content creators who deal in “mainstream” content. Yes, that means more television shows, or even (gasp), movies.
