Of course, sometimes the easiest way to find the show you're looking for is to go straight to the source. The Fox network makes full episodes available one day after shows go on the air. And you can watch the most recent episodes of popular shows like "House," "Grey's Anatomy" and "Modern Family" on their networks' Web sites at no charge.
They're not available to watch live yet, though. And the ABC Web site, among others, notes that some shows are available online for only four weeks after they're shown on the air -- perfect if you fall a couple weeks behind on your favorite show, but not if you've missed the whole season.
