Well, Joost now has something a lot of other video services don't: advertisers. The company, which was started by Skype co-founders Niklas Zennstrom and Janus Friis, said today it has signed three month deal with 32 major advertising, including P&G, Coca-Cola and Visa. Joost plans to make it advertising-friendly environment by offering traditional 30-second mid-roll spots, as well as other formats. It remains to be seen, however, whether 30-second spots will resonate with online couch potatoes, who can change channels with the click of a mouse.
