Porchlight Entertainment was an American production company founded in 1995 in Los Angeles, known for children's and family programming including Jay Jay the Jet Plane and Adventures from the Book of Virtues. Its closing and opening ident became familiar to viewers who saw its shows on television and home video in the late 1990s and 2000s. The brief shhh logo sound later circulated online as a standalone clip on soundboards, where people reuse it for quiet, nostalgic intros and gentle hush jokes long after the original programmes aired.
