Aereo expands to Boston

Aereo, the television-over-the-Internet service that is threatening the broadcast and cable TV industries, is expanding to Boston on May 15.

Aereo will offer 28 broadcast channels, plus the cable channel Bloomberg TV, for about $8 a month. Service will be available in Boston and surrounding areas in Massachusetts, New Hampshire and Vermont.

Aereo announced in January that it plans to expand beyond New York to 22 additional markets. Boston represents the first metropolitan area outside New York. Others expected in the coming months include Chicago, Philadelphia and Washington.

Aereo converts television signals into computer data and sends them over the Internet to subscribers' computers and mobile devices. Broadcast networks, including CBS Corporation, Comcast, News Corporation and Walt Disney Company, have filed lawsuits against Aereo. So far, a federal appeals court has ruled against broadcasters claims that Aereo's service constitutes copyright infringement.
