Online video startup NimbleTV told us that service was just months away, and it's acting on that promise with the official launch of its private beta. The 250-plus New York City residents let into the beta will have the option to stream cable, satellite or other paid TV services to virtually any device with a modern web browser and a good broadband connection. Regular service could be available in the first quarter of 2013 at an estimated $20 per month, although this doesn't include the TV programming in question: NimbleTV's business model requires subscribing to traditional service that the company sets up on the customer's behalf. This is also presuming the provider doesn't encounter any legal obstacles. The fledgling firm lets customers sign up for service outside of their actual region, which could dodge around blackout policies on sports and other shows. If Aereo upset broadcasters by streaming local, over-the-air TV, an even more adventurous company could wind up in the same boat.
