That TMZ is engaging in yet another brand extension – there's the website, the TV show, and you might even be able to count the two dozen emails they send each day as a unit unto itself – is of little import. But TMZ's move to MySpaceTV, where it will have a dedicated video channel, is: It's another team up between the Time Warner website (which is technically a project from subsidiaries AOL and Telepictures) and News Corp. TMZ's television show is produced with Fox Television and broadcast on Fox-owned stations, and now it's new web brand will sit on News Corp.'s social networking site. Jesus, Rupert, just make a bid for AOL already.
