I too think it's great that you're helping him, specifically letting him know someone will always love him. It's a harsh and lonely world out there.
As far as tv goes--I have a 20 year old analog tv and get my local stations. You need a converter box, that changes signal from analog to digital. The govt gave away free cards for them, but they shouldn't be too expensive at discount electronic store. Then he can use rabbit ear or old type antenna. I live in the country and get at least ten channels. Hope this helps.
