During the third quarter of 2006, consumers paid for and download approximately 1.2 million videos from online providers. Of these, about two thirds were TV shows, a quarter were music videos and about 6% were movies. Apple's iTunes store accounted for about 90% of these sales. Vongo came in second with about 5% of sales.
The vast majority of other video downloads? Porn. A Forbes.com article suggests that US consumers downloaded about six million porn videos in the Q3 of 2006, mostly from free illegal sites. The 1.2 million legal video downloads in that time period kind of pales in comparison.
