This is not a bellwether event, perhaps, since demographics plays such a vital part in interpreting it, but the cost of advertising during "The Simpsons" is now higher on Internet service Hulu.com and TV.com than on the Fox network by about twice. This PC World article (by way of SlashDot) exposes other issues which make interpretation difficult: 37 seconds of advertising during an online show versus 9 minutes during a TV/cable broadcast, smaller online viewing audience, and others. No doubt, the chins of many network executives are being scratched contemplatively.
