I'm sure this should be obvious

But so far it isn't.  Suppose you were alone in a hotel room with a big TV and lots of free channels and you wanted to know what was on. Not so terribly long ago nice hotels would leave a copy of the weekly tv guide that newspapers used to publish with their Sunday paper. But I'm not sure that newspapers even do that any more.  Anyway, there's no tv guide here. Surely there must be an Internet site with a nice grid listing what's showing on the major networks and cable stations?  But where?  How do people find out TV schedules these days?
