The FCC regulates and over the air radio frequencies so satellite TV and radio are under the FCC
As for cable the cable companys interconnect to the Internet via the same telecommunication infrastructure the FCC regulates
Also the cable company's and telco (for dsl) as "last mile" provider are granted a government monopoly to provide you service ...
You do not "pick" your phone or cable company, they are utility just like water, gas and electric services
The local government picks the company they will allow to have the easement access to your property to lay the lines to provide you service
On the technical side I will bow to your knowledge, as I do not know. However, content is entirely different. The FCC does not regulate the content of cable and satellite in the manner in which they do so for broadcast radio and TV.
Telecommunications, including rights to lay cable and access utility easements, has been open to competition for many years. Yes, CATV still can have a monopoly franchise in some states/localities, but there are no legal telecoms monopolies anymore. The reason we don't see many competing local infrastructure providers is pure economics.
