MediaPost reports that AirG, the Canadian company that powers mobile communities across providers like Verizon, Vodafone and Virgin Mobile, announced that it reached the 20 million user mark.

AirG works with brands such as Pizza Hut, Axe, and Dunkin' Donuts to create ad campaigns on mobile, cleverly disguised as social networking communities on cell phones.

According to AirG, their users spend an average of about an hour a day in one of these mobile communities. "There is a tremendous opportunity to reach a clearly defined market of mobile social network users--we call them 'Generation G' in-house," said AirG founder Frederick Ghahramani in the article. "And without being pejorative, it's the 18- to-30-year-olds with service-type jobs--like the night security guard, or Starbucks employee who are connected to their mobile phone--not a white collar worker who checks their TD Ameritrade account or uses eBay via their desktop."
