This should not be hard.

But a few months back, when I fired up Hulu to catch up on , I noticed with surprise that there were far fewer episodes available for streaming than had aired on TV. What gives?

Licensing is what gives. On further inspection, I discovered a note on the show's Hulu page:

The first two episodes of the current season will be available the day after air. Subsequent episodes will be available 30 days after their original airdates.

Who the heck is going to wait 30 days to watch a 40-minute television episode? Not me, that's for sure.
