Rob: Speaking on behalf of comScore, I must take issue with the insinuation made in your article that comScore's studies are somehow "suspect" when they're funded by a vendor. I can assure you that whether funded by a client or not, we objectively report what our data are saying. To suggest otherwise is incorrect and irresponsible. I also want to point out that our study of iTunes sales trends was NOT -- as you state -- funded by any client. It was, rather, an analysis we conducted "on our nickel" using the comScore database (which, with 1 million people, is about 100 times the size of the sample Forrester used). I would further point out that the sales growth rate we reported for iTunes(up 84% in 2006 versus the seasonally equivalent year ago period)has been corroborated by independent reports from Piper Jaffrey (using Apple data) and NPD. Additionally, both Nielsen SoundScan and the RIAA have published data showing that total music downloads are up about 70% this year. Only Forrester is claiming that iTunes sales are down -- which Apple itself has strongly denied to be the case. How much more evidence does one need before concluding that something seems amiss with the Forrester report? Gian Fulgoni Chairman comScore
