The BBC has made good on its October promise to launch six new video channels on YouTube in Urdu, Spanish, Russian, Persian, Portuguese and Arabic and has rolled out its Russian stream.

The BBC Russian YouTube channel will feature footage from BBC Russian correspondents and Russian-language reports on major news events.

The other multi-language channels will be launched between now and early 2009, a press release from the corporation said.

YouTube is getting in on the act again ahead of the World Economic Forum at Davos next month by asking users to send their video answers to the following questions:

Are you confident that global growth will be restored in 2009?
Will the environment lose out to the economy in 2009?
Will the Obama administration improve the state of the world in 2009?
Should company executives have a code of ethics similar to doctors and lawyers?

The best clips, which can be uploaded to the site’s Davos channel, will be broadcast at the forum during sessions; while the user who creates the best video, as voted for by other YouTubers, will have the opportunity to attend the event, all expenses paid, as a citizen reporter for YouTube.

In a repeat of last year’s event, a YouTube booth for attendees of the forum to upload their video responses to the debates will also be available, according to a press release.

This seems to be just one strand of the forum’s multimedia activities. It’s also represented on Twitter, MySpace, Facebook, Flickr and  questions for press conferences can be submitted via Qik and Mogalus.
