Dive Insight: 

Millennial Media's struggle to scale and handle programmatic is common among ad networks. The more firms are able to combine technology, tools, and talent — the better the overall ad networks will become. Seems like Nexage was a perfect fit for the expansion and development Millennial is planning.
