eMarketer estimates that Google is the 900lb gorilla in the US market this year, accounting for 54.5% of mobile ad revenues. But second place is taken by Pandora (8.7%), ahead of Twitter (5%), ad network Millennial Media (3.2%), Apple’s iAd division (2.9%) and Facebook (2.8%). Even by 2014, eMarketer thinks Pandora will still be in third place with 7.5% of US mobile ad revenue – behind Google and Facebook, but still ahead of Twitter.
