I have used this book to teach a class on American Television to students in Germany. It's great to have realiable and easily accessible information on when certain shows were first aired, how long they ran for, what their central concerns and distinctive features were etc. Scholars, students, as well as TV fans will find a good first overview concerning the shows that interest them. Of course the individual entries are not very extensive, but they provide a good basis. A useful history of television in America precedes the entries on hundreds of shows.
Highly recommended for general readers as well as experts.
