The Largest Mobile Ad Networks?

PaidContent has used Nielsen data (from an article in Mobile Marketer) on unique visitors to compile a list of the largest mobile ad networks. Here's the list according to the site (based on monthly unique reach in the US):

  1. Millennial Media: 45.6 million
  2. Yahoo!: 36.1 million
  3. Google: 31.9 million
  4. AOL/Platform-A’s Third Screen Media: 28.6 million
  5. AdMob: 25.7 million
  6. Microsoft: 25.4 million (doesn't include the new Verizon deal)
  7. Jumptap: 23.4 million
  8. Quattro Wireless: 23 million

I invite the companies on the list (or comScore) to dispute it and provide their numbers.
