eMarketer revises estimates of mobile marketing up to $2.6 Billion:

eMarketer estimates mobile advertising spending in the US reached $1.45 billion in 2011, up 89% from $769.6 million in 2010. This year, US mobile ad spending will grow 80% to $2.61 billion.

This is the time of year when Google places an earnings call for its investors and uses the opportunity to provide insight into its profits and revenues. On Thursday Google CEO Larry Page revealed that display ad revenues are currently running at $5 billion per year, up from just $2.5 billion 12 months ago.

2011 was a year that everyone is happy to have survived. Some advertisers and networks crashed while others thrived. It was a year in which financial stability, ability to pay on time and the smarts to avoid legal issues became mission critical competitive advantages for many networks. All of these factors affected the new BLUE BOOK Top 20 rankings for performance marketing networks. And the changes in our approach mean that the rankings - to be announced at Affiliate Summit on Sunday - are the biggest and most authoritative yet.
