Scripps Networks Interactive was formed in July of 2008 as a spin-off from their cable network. They have locations in many major cities. They did not announce any plans for a merger. However, Google is working hard on negotiating deals with other individual networks, so that YouTube TV is constantly adding more channels.
I would suggest that you keep an eye on it if you are interested. I received several announcements of additional channels already since I started subscribing to YouTube TV.
