For the visual learner, television is certainly a boon. Such stations as the History Channel present actual films from major historical events as well as dramatizations of others. The Arts and Travel channels transport viewers all over the world without cost. Educational channels present concerts of various types of music as well as live dramatic performances. In short, viewers can be exposed to cultural experiences of various types. In addition, the programs that are about home improvement, sewing, cooking, etc. are also informative and enlightening.
Of course, the medium of television provides up to the minute news, weather, and other important information that people need daily. When there are political discussions such as the presidential debates, viewers can watch and deliberate upon what each candidate says.
At a 1958 convention in Chicago, Illinois, CBS anchorman Edward R. Murrow, a pioneer of television news broadcasting made this comment about the new medium, television:
This instrument can teach, it can illuminate; yes, and it can even inspire. But it can do so only to the extent that humans are determined to use it to those ends. Otherwise it is merely wires and lights in a box.
Television is surely one of the most influential technological developments for our daily lives. As it reaches almost the totality of households in the United States and the Western world, TV has become an important point of reference for educational agencies which can broadcast their programmes and documentaries through television. The problem with educational television is that it tends to be marginalized in the broadcasters' programming and receive short amounts of time (see the third link below).
On the negative side of the argument (how can the non-educational content of tv be limited), there are also rules and regulations that TV networks must respect as far as obscene content is concerned (see the second link below), although this raises questions on what is obscene and who defines it as such. It also raises questions on government control and censorship.
