The Register is reporting that Apple’s iTunes has suffered from a collapse in sales revenues this year. Secretive Apple doesn’t break out revenues from iTunes, but Forrester conducted an analysis of credit card payments over a 27-month period. And this year’s numbers aren’t good. While the iTunes service saw healthy growth for much of the period, since January the monthly revenue has fallen by 65%, with the average transaction size falling 17%. Forrester revealed some fascinating details about iTunes purchasing habits. Some 3.2% of online households (around 60% of the wider population) bought at least one download, and these dabblers made on average 5.6 transactions, with the median household making just three a year. The average transaction per household was slightly under $3.
