I used Netflix to catch up on The Fosters and Switched at Birth (I was at least a season or two behind on each series)
Orange Is the New Black
Desperate Housewives (I watched the series every Sunday night when it was first airing so I watched it again now that I'm older and it's much funnier now)
Skins (UK version)
I'm currently watching Friends and my boyfriend uses mine to watch Breaking Bad.
A few summers ago, my cousin and I attempted to watch every SNL episode ever.. We made it all the way to 1989 or so before school began back up, lol.
I used Hulu to catch up on Glee when I stopped watching for a year and I watch a lot of HGTV house flipping shows, rehab addict, ect. And I'm never able to watch my shows live (Eye Candy, Switched at Birth, The Fosters and Glee) so I still use Hulu and abcfamily/mtv websites.
