Lip Sync Battle is an American musical reality competition television series which premiered on April 2, 2015, on Spike, later known as Paramount Network. The show is based on an idea by Stephen Merchant and John Krasinski, in which celebrities battle each other with lip sync performances. The idea was first introduced as a recurring segment on Late Night with Jimmy Fallon, which later transitioned into The Tonight Show Starring Jimmy Fallon before being developed into a separate show.
The premiere episode was the highest-rated premiere in Spike's history. Lip Sync Battle has been a hit show for the network. The series' success has led to the creation of various international adaptations. In August 2018, the show was renewed for a fifth season which premiered on January 17, 2019.
On September 22, 2020, it was announced that the series would move to another ViacomCBS network as part of the Paramount Network's upcoming shift to movies.
