Why did Dr. Strauss give charlie a television?

The machine was actually a teaching machine, meant to teach Charlie while he was sleeping.

He brout me a presint only it wasnt a presint but just for lend. He said its a teeching mashine that werks like TV. It talks and makes picturs and I got to tern it on just before I go to sleep. I said your kidding. Why shoud I tern on a TV before I go to sleep. But Prof Nemur said if I want to get smart I got to do what he says. So I told him I dint think I was goin to get smart anyway.
