NEW YORK (AP) — The Supreme Court dealt Internet startup Aereo a major setback on Wednesday in ruling that the television-over-the-Internet service operates much like a cable TV company. As a result, the service violates copyright law unless Aereo pays broadcasters licensing fees for offering TV stations to customers’ tablets, phones and other gadgets.

Aereo was still operating Wednesday afternoon without paying such fees, as the U.S. District Court in New York must still implement the Supreme Court’s findings. But Aereo’s options are limited. The ruling may also affect other Internet services, though the Supreme Court did try to limit the scope of its decision.
