CBS may have wound up creating a new network programming model after scoring a hit with its limited summer series "Under the Dome." The 13-episode series, which had its stream rights presold to Amazon.com, attracted more than 11 million viewers each week. "Because of the Amazon deal and because of the international sales, we were able to make the show profitable even before it went on the air," CBS chief Leslie Moonves said during an earnings call with analysts. "Now the fact that it is a huge hit is really almost gravy. It will bring in a ton of profits into the third quarter."
