NEW YORK — Aereo, the start-up that offers live television broadcasts over the Internet starting at $8 a month, said it will start service in the Atlanta market on June 17, following an expansion to Boston on Wednesday.
Until this week, the service had been available only in the New York City area.
Aereo said Tuesday that it will offer 27 Atlanta-area broadcast channels, plus the Bloomberg TV cable channel. Service will be limited to residents of 55 counties in Georgia, Alabama, and North Carolina.
Aereo converts television signals into computer data and sends them over the Internet to subscribers’ computers and mobile devices.
Aereo sells its service as a low-cost alternative to cable or satellite TV, and it plans to target those who have dropped pay-TV service or never had it.
Broadcasters see Aereo as a threat to their revenue as they increasingly supplement advertising revenue with fees they get from cable and satellite TV companies for redistributing their stations to subscribers.
So far, federal courts have ruled against broadcasters’ claims that Aereo’s service constitutes copyright infringement. Aereo claims what it is doing is legal because it has thousands of tiny antennas at its data centers and assigns individual subscribers their own antenna.
