So now that we know the identity of the actor to play the next Doctor on Doctor Who, the Telegraph newspaper in the U.K. is now beginning speculation on the identity of the Doctor's next traveling companion. Since this is speculation, I would take it with a grain of salt. At least it's not from the other British "newspaper" the Sun.

They seem to think that the BBC and the producers will go with the semi-famous pop star route that proved successful with Billie Piper (The article throws out names like Lily Allen). It's a safe bet that whomever the Doctor's next companion is will be young and female.

Given the complete history of the show, companions have run the gamut. Since the reboot, I liked Rose and Martha and adored Donna (up until the end, which I fell flat a bit). For his remaining specials, David Tennant's Doctor will be pretty much companion-less. Who would you like to see join the next Doctor for a romp in the TARDIS?

During tonight's long-awaited new episode of Heroes, NBC will launch TV 360 on NBC.com. It's the most extensive online companion that NBC has produced for any show. Viewers who sign up for Heroes 360 will get mobile content, access to a WAP (Wireless Application Protocol) site that one of the characters gives them access to, a phone number to Primatech Paper Company, and there will be original videos such as cast commentary. NBC execs tout it as "the most developed TV 360 application we've created for a scripted series, and the first to use this level of interactivity," according to Jeff Gaspin, NBC-U cable entertainment president. And of course there will be a lot of ads for Nissan.

After the big disappointment that was The Lost Experience, it's hard to get excited about online companions to television shows. Will you give this one a try? What do you actually expect to get out of it?
