BTW, Turner Classic Movies and the Hallmark channels have been consistently popular channels since those channels first came to cable and satellite. People are more than willing to upgrade their cable/satellite packages to get them, even with the presence of Hallmark Movies NOW as a streaming app.
Upgrade their cable/satellite bundle to include channel packages that include them? If every channel is a la carte, then it could be that all the channels in those packages drop below the threshold of "niche".
Yes, Turner Classic Movies and the Hallmark channels are very valuable cable properties. There's a reason why Hallmark Cards won't sell those channels to the likes of, say, A&E Networks (which have their own valuable properties in Lifetime, LMN, and History).
Compare this to, say, regional sports networks. Both NBC/Comcast and ATT are trying to sell their regional sports channels due to not wanting the headache anymore. And when it comes to Bally Sports channels, let's just say those 22 channels would not fetch the estimated $3 billion net present value (down from the original asking price of $20 billion in 2019, and still down from the $10 billion they did get from a subsidiary of Sinclair) if Bally Sports was forced into Chapter 11 bankruptcy.
Think about THAT the next time someone tells you sports is supposed to be cable/satellite's savior.
