iTunes use increased in 2006
Macworld points to this report that claims that iTunes usage nearly doubledgrew a lot in 2006. Growing by 47.5%, the number of unique Apple iTunes users outpaced the growth of RealPlayer (9.1%), QuickTime (8.7%) and Windows Media Player (2.0%). These numbers derive from Neilsen/NetRatings. One presumes that many of those installations relate directly to iPod sales. I expect the introduction of AppleTV (should it ever get around to shipping because darn it I am sick of waiting) to boost iTunes installation numbers as well.
