The most-watched TV drama is "NCIS" on CBS. The biggest comedy is "The Big Bang Theory," also on CBS.
So those shows should be the most expensive to advertise on, right?
Advertising Age has come out with its annual look at what commercials cost on broadcast TV shows. Even though CBS has some of the most popular shows on television, it is not getting the most money for commercials on its hot programs.
A 30-second spot on "NCIS" costs $166,649, according to Advertising Age. A commercial on NBC's "Sunday Night Football" runs $545,142. So far this season, "NCIS" is averaging 20.5 million viewers compared with 20.4 million for "Sunday Night Football."
It costs almost $331,000 to advertise on ABC's "Modern Family," which is about $60,000 more than a spot on "The Big Bang Theory," even though the latter has a bigger audience.
