Aereo, the online TV startup that streams over-the-air broadcasts via tiny, individual antennas, said Monday it will launch in Austin, Texas, on March 3. This follows its rollout in San Antonio last week and an expansion to Dallas/Fort Worth and Houston last year. However, the announcement also comes a week after a US District Court in Utah became the first in the country to temporarily shut down the service, a rare legal win for the broadcasters that are taking Aereo to the Supreme Court later this year.
