No. In fact, the local city directory for 1927 has a radio dealer that also sold "Television apparatus." There were no regular experimental broadcasts here at the time, so I suspect it was for the hobbyist.

This is correct. Television in the late 1920s was purely experimental with no over-the-air broadcasts. By the mid-to-late 1930s experimental broadcasts were being made over the airwaves. President Roosevelt's dedication speech at the New York World's Fair was broadcast live on NBC's New York channel.
According to an edition of the Complete Directory to Prime Time Television, the first network broadcasts were some newscasts on NBC in 1944. The first network entertainment broadcasts were over a three-station network put together by NBC in 1946. They had networking all to themselves briefly. DuMont was the next network to broadcast over two stations.
CBS and ABC held off until 1948. ABC was the red-headed stepchild of NBC and actually broadcasts their programming over DuMont for a brief time because they had no studios in New York. CBS was late in the game because they wanted to have their color system (a mechanical system involving a rotating wheel) approved over RCA's electronic black-and-white system. CBS lost and went into network broadcasting in 1948.
I've heard it said that one reason for Paley's great talent raid on NBC was to set up CBS to be the leader in television. I don't know how true that is, but it kind of makes sense.
