Opportunity Knocks (British TV series)

Unlike its rival New Faces, the winning acts on Opportunity Knocks were decided not by a panel of experts but by the viewing public. In the ITV version this took the form of a postal vote, the winner of which was announced the following week. The BBC revival was notable for being the first TV show to decide its winner using the now-standard method of a telephone vote. In both versions the studio audience reaction to each act was measured by a clap-o-meter, but this did not count towards the final result.

The programme was recorded the Friday before transmission, so votes had to be in by Thursday. They also, according to host Hughie Green, largely to ensure fairness, had to be in "your own handwriting".

Although Opportunity Knocks did produce a number of talented acts, the method of putting the contest to a public vote did sometimes result in victories for novelty acts, in particular those involving children or animals. On one notorious occasion, the young Su Pollard was beaten into second place by a singing dog.

For the Monkhouse-fronted revival, the voting system was radically changed, making it the first British TV show to use telephone voting in order to get a more immediate result (although an updated electronic "clap-o-meter-style" on-screen indicator, using stars, was used during the show). The telephone voting system is now common on British TV.

Entertainers who appeared included Freddie Starr and the Delmonts, Su Pollard, Paul Daniels, Darren Day, Pete the Plate Spinning Dog, Los Caracas, later to become Middle of the Road, Mary Hopkin, Bonnie Langford, Les Dawson, Maureen Myers, Barry Cummings, Royston Vasey (later to find fame as Roy 'Chubby' Brown), Little and Large, Bobby Crush, Berni Flint, Tony Holland (The Muscle Man), Millican & Nesbitt, Neil Reid, Peters and Lee, Lena Zavaroni, Frank Carson, Max Boyce, Pam Ayres, Juniper Green, Gerry Monroe, Debra Stephenson, Tammy Jones, Paper Lace, Barry and Paul Elliott and Tony Monopoly. Several winners of Opportunity Knocks (notably Tammy Jones, Champagne, Tony Monopoly) later attempted to represent the UK at the Eurovision Song Contest, taking part in the A Song for Europe competition. Lee Evans appeared in 1986 but was rejected and did not make it past the initial audition. Kaz Hawkins appeared in the 1980s' revival as a child.

Today, most of the elements of this show are visible on the ITV talent search Britain's Got Talent, which was created by record company executive Simon Cowell. The method of deciding a winner by telephone is used on that show and many other similar programmes around the world.

A reference to the show can be heard on the Beatles' first live performance of "Yesterday" at Blackpool Night Out. George Harrison introduces the song, saying "For Paul McCartney of Liverpool, opportunity knocks!". This version appears on Anthology 2.
