TVParty.com hosts many clips of "bloopers" -- funny outtakes from a recorded production -- from classic TV shows, including "General Hospital," "Star Trek," "MASH" and "The Carol Burnett Show," on its website. A blooper commonly occurs as a result of an unintended incident, such as a prop failure while filming, a forgotten line of dialogue or an actor breaking character. Television news, because it is broadcast live, is a frequent source of on-camera blunders.
The television show "TV's Bloopers and Practical Jokes," hosted by Dick Clark and Ed McMahon, was a popular vehicle for clips of American television blunders beginning in 1984. It ran regularly through the 1990s and sporadically until 2007 and was revived briefly in 2012. It was popular enough to inspire many spin-offs and imitators, such as "TV's Censored Bloopers" and "Celebrity A-List Bloopers."
A television show sometimes airs a "gag reel," which is a vignette of clips of mistakes made on camera during production. They are often shown during closing credits or included as a special feature on a DVD.
YouTube hosts millions of videos, many of which are outtakes from television shows all over the world. Several full episode of the "TV's Bloopers and Practical Jokes" and similar shows are available there, as of 2015.
The term "blooper" is a portmanteau of "blue pencil," the tool traditionally used by editors to indicate cuts.
