ITC Entertainment was a British production and distribution company founded in 1954 by Lew Grade, behind series such as The Prisoner, Thunderbirds and The Muppet Show. Its spinning logo ident and accompanying fanfare became familiar to generations of viewers at the start of programmes sold around the world. Clips of vintage idents later circulated on video platforms and nostalgia forums, where editors began lifting this fanfare for ironic prestige intros. It remains popular because it instantly evokes classic television, even for viewers too young to have seen it live.
