Loosely based on The New York Times bestselling series from Sara Shepard, ABC Family’s Pretty Little Liars has a devoted fanbase. This young adult TV series follows the teenage clique—The Liars—after their Queen Bee Alison DiLaurentis disappears, only to have the character “A" leave them anonymous messages leading them closer to finding Alison. #PLL uses Twitter as a “modern-day fan club," promoting their show and other teen obsessions on @ABCfamily/#Freeform. Social media is important not just in promoting the show but in the show itself. Characters follow each other on Twitter, blending fact and fiction, which fans say contributes to high relatability.
