From novels to streaming, how a teen mystery franchise conquered American television screens

In short: Beginning with a 2006 novel, the Pretty Little Liars franchise evolved into a sprawling multimedia empire. Spanning four television series, a web series, and an audio podcast, the saga of Rosewood and its secrets captivated audiences for nearly two decades, blending teen drama with high-stakes mystery and supernatural twists.

The franchise originated from Sara Shepard’s young adult novel series, which follows four friends whose clique disintegrates following the disappearance of their leader, Alison DiLaurentis. The narrative hook—anonymous threats from a figure known as A—became the foundation for a television adaptation that premiered on ABC Family in 2010. Developed by I. Marlene King, the show became a cultural phenomenon, running for seven seasons and concluding in 2017 with a finale that drew an estimated 1.41 million viewers.

Beyond the core series, the franchise expanded through various spin-offs and sequels. The supernatural-themed Ravenswood aired in 2013, followed by the stand-alone sequel Pretty Little Liars: The Perfectionists in 2019, which brought back characters Alison DiLaurentis and Mona Vanderwaal. The final installment, a series launched on HBO Max in 2022, shifted the focus to a new cast dealing with the consequences of their parents' past actions. Despite the popularity of the original show, many of these subsequent projects faced cancellation after only one or two seasons.

The franchise's reach extends into diverse media formats, including a web series titled Pretty Dirty Secrets and an audio sequel released on Audible in 2022. While the original series was loosely based on Shepard's books, the later iterations, such as the 2022 HBO Max series, integrated new storylines into the established chronology. Today, the franchise stands as a significant example of how a singular mystery premise can be adapted, reworked, and extended across multiple platforms to maintain relevance with shifting audiences.
