NBC, and its regional sports networks, are no longer available in Channels via TV Everywhere providers. NBC is still, and will continue to be, available via over the air antennas.
NBC has adjusted their streaming technology to a format that is incompatible with Channels. This is not something that we can adapt to, and ends compatibility with Channels.
My NBC channel is still working
Your NBC affiliate has not migrated yet but it will within time. So while it works right now, it assuredly will become unavailable.
Is there an alternative way to get NBC into Channels?
You can add NBC, and all of your local channels, with an antenna and HDHomeRun networked TV tuner. Add this to your Channels setup to add all the free channels you receive locally via your antenna.
Will other NBC owned networks be affected?
At the time of writing, all other NBC owned networks are still working. We expect them to transition to the new streaming technology in the future and will eventually become unavailable in Channels as well. But time will tell.
UPDATE: Unfortunately all other NBCU networks, Bravo, E!, OXYGEN, SYFY, USA, GOLF, MSNBC, and CNBC have stopped working with our TVE integration.
