Nice rundown: Some prices of premium ad placements at big sites

A good list via What Online Ads Really Cost | Digiday.

Yahoo home page takeover costs $450,000

Youtube home page takeover costs $400,000

Facebook logout screen ad: $100,000

AOL home page takeover: $400,000

And I like this little gem at the end on how much a mobile app costs brands:

Branded mobile app = $125,000
There’s been a lot of talk about what a mobile app should cost to produce, but according to one brand marketer, they typically sell for between $100,000 and $150,000, based on functionality. That doesn’t include the media to promote or distribute it, though.
