Television? Not much TV before 1950; but some. Worth noting that RADIO MIRROR added "AND TELEVISION" to its title in the early 1940's. In Britain, of course, there were TV broadcasts beginning in the early 1930's.
Radio? Yes, although there are fewer magazines about Radio than you might think. We cover the technical aspects of Radio, including a lot of its early history as a geek phenomenon, in the Science and Technology Category.
Movies? Yes! Dozens and dozens of magazines published thousands of issues featuring the latest from Hollywood (and occasionally from elsewhere). Looking at these you find a short-form pop cultural history. You can read a great number of these actual magazines via the Media History Digital Library! Check out their section linking to hundreds and hundreds of issues online; it's the easiest way to find them.
