Invention of TV began in 1922 in Rigby, Idaho, the hometown of Philo. At the age of 16, Philo was a very shy boy. Only his teacher, Justin Tolman, realized that Philo was a special person.

One day after school Mr Tolman found Philo in the schoolroom. The boy was making drawings on the blackboard.

“What are you doing?” Mr Tolman asked with interest. “What are these drawings?”

“I want to invent things,” Philo answered, “and these are the drawings of one of my first inventions. I have an idea for a way of sending pictures through the air. Please, just let me tell you about it. You are the only person who can understand what I have done.” In the school library Philo had read about a man who had worked on an idea for TV, but had failed. Philo was sure that his idea was better and that he could succeed.

Mr Tolman was not sure and asked Philo many questions about the drawings. Giving facts and figures, Philo answered every question.

In 1926, Philo sent his drawings to Washington, along with a letter asking for patent (专利)rights on TV. Since then, television has become an important business all over the world.
