Once, on an episode of the TV sitcom “Leave it to Beaver,” Beaver asked his dad if he could “look at” (instead of “watch”) television. I found that expression so odd (as if TV were an art object), but I wonder if was common 60 years ago?
When I teach this point, I tell students that we look at things that are basically stationary, and we watch things that are moving. We look at the TV set (a stationary piece of furniture), but we watch TV (because there is action on the screen.) Looking and watching are both things that we do intentionally, whereas we often see things without deliberately trying to do so.
