Well, as per the post on the Nerdy.FM facebook:
Due to unforeseen and uncontrollable circumstances, Nerdy.FM’s final broadcast day will be on Monday, August 21st, 2017.
It’s been an amazing ride and we thank you all for making it possible. Stay tuned for news about special farewell programming and keep the geek party going over at our mothership, The Nerdy Show Network (including the debut of a monthly Nerdy FM podcast!)
There’s more details which I’ve gone into on the Network Patreon and will most likely discuss in an upcoming episode of Nerdy Show. Unfortunately this is a bullet we can’t dodge.
