The news outlet was once co-owned by Charles Dolan and his son, Patrick, who now owns it.
While on a family vacation, Dolan was mulling a problem facing his company, Sterling Manhattan Cable.
Dolans solution: The Green Channel.

I grew up on radio and radio was free.
Then television arrived and it was free, too.
As the city experienced upheaval and financial duress throughout the 1970s, Dolan set his sights on the suburbs.
Cablevisions headquarters were established on Long Island, eventually taking over a former Northrop Grumman facility in Bethpage.
Later renamed AMC Networks, it spun off from Cablevision in 2011.
It spawned the News 12 Networks group of local news channels in the New York area.
Cablevision was sold in 2016 to French telecom firm Altice for $17.7 billion.
The company continues to provide TV, broadband and wireless service outside of New York under the Optimum brand.
Our thoughts are with the entire Dolan family and the countless people Mr. Dolan influenced throughout his remarkable life.
We do not expect this to directly or indirectly change ownership by the Dolan family.
