YouTube is officially allowing video creators to sell their own ads, after Googler Jordan Hoffner revealed the then-informal program in an interview with TV Week two months ago. Online video production company Revision3 is listed as one of the participating companies, with a GoDaddy campaign. Interestingly, content partners will also be able to sell ads against other YouTube videos in the same subject vertical — so Revision3 could sell ads that play against other technology-oriented programming on YouTube.
