BAMTech Media is a direct-to-consumer streaming company whose cutting-edge technology underpins some of the biggest streaming services in the world, including ESPN, HBO, WWE, and Fox Sports. The company made its name building streaming services that transformed the way that fans consumed sports. For instance, it created MLB.TV, which allows baseball fans to watch out-of-market games, as well as the At Bat smartphone app, which is the highest-grossing sports app of all time. It has a reputation for being able to deliver tens of millions of live streams at a time without serious glitches, and for being able to limit churn among viewers. In 2017, Disney bought a majority stake in the company and tasked it with building Disney’s two upcoming streaming services—a new ESPN app that will launch in 2018 and an entertainment app that will debut in 2019.
