Of course, what the article doesn't clearly convey is that there are many many more companies who can advertise on the internet compared to those who can afford to advertise on TV - the cost differential is huge, so it's not surprising that internet advertising revenues would eventually outgrow it.

What would make interesting reading is a study on the companies who _do_ advertise on TV and to see how much of their TV budget has been trimmed (if at all) and what they spend on internet advertising instead.
