The invention of the television has had a huge impact on our lives. It entertains. It informs. It teaches. It wastes time. Philo Farnsworth, the inventor of the television, envisioned it as a teaching tool.

The television has been both praised and defamed. Some households have one in almost every room. People watch television on computers, tablets and even cell phones.

The number of channels and shows has increased enormously in the last 10 years. From over the air free television to cable and satellite, there is no denying that television is a big part of everyday life.
