The A.V. Club is an entertainment website featuring reviews of films, music, television, books, games and DVDs, as well as interviews and other regular offerings examining both new and classic media and other elements of pop culture. The A.V. Club was initially created in 1993 as a supplemental part of The Onion and had a minimal presence on The Onion’s website in its early years, but in 2005—during a website redesign—its online identity grew and matured in ways that allowed it to have an identity all of its own. Unlike its parent publication, The A.V. Club is not satirical.
The publication’s name is a reference to school audiovisual clubs, "composed of a bunch of geeks who actually knew how to run the filmstrip and film projectors." Source
