Did you know these TV shows were based on books?

We all know that many movies are based on books, but did you know several television shows we know and love are based on them as well?

In the future, I hope to be able to post some comparisons between books/book series and their tv equivalents. Here are some of the books turned television series I've been able to come up with...

This show is based on a love triangle between a girl named Elana, and two vampire-brothers named Stefan and Damon.
