Aereo's streams in Denver and Salt Lake City hung on for a while after the US District Court of Utah granted its opponents a preliminary injunction on February 20th, but today they're shutting off. Yesterday a panel of federal court judges denied Aereo's request to stay the injunction while it appeals, claiming "Aereo has not made a strong showing that it is likely to succeed on the merits of its appeal. Nor has Aereo demonstrated that the other factors weigh in its favor." As a result, the antenna-to-streaming company has informed affected customers service will go dark today at 10am. For now, it's looking forward to the upcoming Supreme Court case to affirm its belief that the service is legal, and issuing a refund for this month's service for anyone living in those two markets. Aereo's hearing is set to take place April 22nd -- check out CEO Chet Kanojia's message to customers after the break.
