Disney is acquiring a 33 percent stake in the streaming video unit of Major League Baseball’s MLB Advanced Media tech arm. The deal values the unit, dubbed BAM Tech, at $3.5 billion. Terms of the deal also reportedly include a four-year option for Disney to purchase an additional 33 percent stake. The deal raises the prospect that Disney “is poised to expand its range of online-video services,” reports Variety. “The league formed MLBAM in 2000 to launch MLB.tv, one of the earliest Internet-delivered video subscription services. Since then, it has grown the division to operate streaming services of several other companies — including Disney’s WatchESPN.”
