"When I was growing up, my parents had a 20-inch Sony Trinitron television. There was a 25-inch model, but having a TV that big seemed vulgar. When I would ask my father why he didn’t splash out for the bigger set, he would say, “Who am I, George Lucas?” 

It seems almost quaint now. These days you would be hard-pressed to even find a 20-inch display. Maybe there is a L’il Couch Potato model from Fisher-Price that runs that small, but TVs continue to grow at a steroidal rate. Last year, the size of the average TV sold in North America was 38 inches, and you can buy an 80-inch model for a little more than $4,000."
