Who created the lip sync battle...
The original "lip sync battle" was created by Stephen Merchant and husband and wife duo, John Krasinski and Emily Blunt. The lip sync battle game had it's first debut on Late Night with Jimmy Fallon.
When lip sync became popular...
I can't find exactly when lip sync started, but I found a sort of time frame. It became popular sometime between 1989 and 1990. By popular, I mean that many singers started lip syncing to their songs.
