Adjab is reporting that Rocketboom, somewhat recently relaunched with new host Joanne Colan, has gotten another sponsor. Chris over at AdJab thinks that this will be interesting to watch - and I agree. During a recent foray into the iTunes music store, I noticed that I couldn’t find Rocketboom anywhere in the Top 100 downloaded podcasts - in which it used to firmly reside. I wonder how much of a turnover in viewers its had since the change in hosts - and how thats affected their ability to get sponsors?
