Nielsen is now tracking mobile games in an effort to expand in a streaming TV world

Nielsen (you know, that group that’s always going on about TV show ratings) is entering a new entertainment market.

The company revealed today that it is going to start gathering data and insight on mobile games. It’s calling the new program Mobile Game Tracking (MGT), and Nielsen will base it off of info gathered from a group of 1,200 mobile gamers each week. The mobile industry was worth $34.8 billion in 2015, according to market research firm Newzoo. Any data that shows which games are the most popular can help developers make more successful titles.
