Social Networks need a new ad (?) model.

eMarketer projects US social network ad spending will fall in 2009.

Problems at MySpace are the main reason for the revision.

As a result of the expected shortfall at MySpace, eMarketer now forecasts that total US social network ad spending will fall 3% to $1.14 billion in 2009, from $1.18 billion in 2008.

Here the article. Emarketer.

"Total social network ad spend in the US will fall from $1.2bn to $1.1bn (£795m) in 2009, mainly due to brands spending 15% less on News Corporation's MySpace, according to eMarketer's revised estimates."
