How do you discover new movies and shows to watch?

I'm curious how others find new movies and tv shows to watch. For me, I used to use IMDB's "related" section. It basically showed you 6 things related to what you were currently looking at. Now I obviously don't go back to IMDB, so I'm experimenting with other discovery methods. I find TasteKid can be pretty accurate - just type in a show you like and it gives you similar recommendations. Also just googling "xxxxx similar shows" sometimes works.

What do you do?
