One argument over net neutrality is the fear that the large Cable TV providers like Comcast controlling internet access as ISPs could charge for various levels of service on the internet in tiers, like they do with Cable TV services. Some people object to that because they believe "the internet should be free."
Entertainment such as radio and television started out as broadcast media, in that you had a receiver in your home to receive the signals broadcast by the local stations. Television grew out of radio. In the early days of television, the 1930s and 1940s, the successful television networks were the ones that started with radio networks.
There are still "free" televisions stations in that you can find many local stations that broadcast a signal through the air that you can receive. Cable TV was initially created to provide television service to areas that did not receive a good broadcast signal. As cable TV expanded in the 1960s and 1970s the Cable TV operators began to add extra channels to their systems that were not derived from broadcast signals.
The internet of today is the next step in the evolution of entertainment. The internet is new way to deliver various content to your homes through wires provided by your Cable TV company that were once used just to deliver television service. Satellite services once developed to compete with cable TV services now also deliver internet access. Radio has also expanded beyond the traditional through the air broadcasting to satellite radio and internet radio.
