As the second-largest mobile ad network, and the top independent one, Millennial Media is the first to try to get an exit the old-fashioned way. It filed its S-1 documents today as the first step in going public, having nearly achieved profitability.
According to the filing, its revenues grew to nearly $70 million in the first nine months of 2011, a 138% increase over the same period in 2010; net losses, meanwhile, declined from $5.4 million to $417,000.
