<i>The Crocodile Hunter</i> Australian television program (1996–2007)

The Crocodile Hunter was a wildlife documentary television series hosted by Steve Irwin and his wife, Terri. The show became a popular franchise due to Irwin's unconventional approach to wildlife. It spawned a number of separate projects, including the feature film The Crocodile Hunter: Collision Course and two television spinoffs: Croc Files and The Crocodile Hunter Diaries.

<i>Night Gallery</i> American anthology TV series (1970–1973)

Night Gallery is an American anthology television series that aired on NBC from December 16, 1970, to May 27, 1973, featuring stories of horror and the macabre. Rod Serling, who had gained fame from an earlier series, The Twilight Zone, served both as the on-air host of Night Gallery and as a major contributor of scripts, although he did not have the same control of content and tone as he had on The Twilight Zone. Serling viewed Night Gallery as a logical extension of The Twilight Zone, but while both series shared an interest in thought-provoking dark fantasy, more of Zone's offerings were science fiction while Night Gallery focused on horrors of the supernatural.

<i>My Three Sons</i> American television sitcom (1960–1972)

My Three Sons is an American television sitcom that aired from September 29, 1960, to April 13, 1972. The series was broadcast on ABC during its first five seasons, before moving to CBS for the remaining seven seasons. My Three Sons chronicles the life of widower and aeronautical engineer Steven Douglas as he raises his three sons.

<i>Ironside</i> (1967 TV series) American TV crime drama, 1967–1975

Ironside is an American television crime drama that aired on NBC over eight seasons from 1967 to 1975. The show starred Raymond Burr as Robert T. Ironside, a consultant for the San Francisco police department, who was paralyzed from the waist down after being shot while on vacation. The character debuted on March 28, 1967, in a TV movie entitled Ironside. When the series was broadcast in the United Kingdom, from late 1967 onward, it was broadcast as A Man Called Ironside. The show earned Burr six Emmy and two Golden Globe nominations.

Broadcast syndication is the practice of content owners leasing the right to broadcast television shows and radio programs to multiple television stations and radio stations, without going through a broadcast network. It is common in the United States where broadcast programming is scheduled by television networks with local independent affiliates. Syndication is less widespread in the rest of the world, as most countries have centralized networks or television stations without local affiliates. Shows can be syndicated internationally, although this is less common.

<i>Family Matters</i> American television sitcom (1989–1998)

Family Matters is an American television sitcom that originally aired on ABC for eight seasons from September 22, 1989, to May 9, 1997, then moved to CBS for its ninth and final season from September 19, 1997, to July 17, 1998. A spin-off of Perfect Strangers, the series was created by William Bickley and Michael Warren, and revolves around the Winslow family, an African-American middle class family living in Chicago, Illinois. Midway through the first season, the show introduced the Winslows' nerdy neighbor Steve Urkel, who was originally scripted to appear as a one-time character. However, he quickly became the show's breakout character, joining the main cast.

A television pilot in United Kingdom and United States television, is a standalone episode of a television series that is used to sell a show to a television network or other distributor. A pilot is created to be a testing ground to gauge whether a series will be successful. It is, therefore, a test episode for the intended television series, an early step in the series development, much like pilot studies serve as precursors to the start of larger activity.

<i>Little House on the Prairie</i> (TV series) American western drama television series

The Bold Ones is the umbrella title for several television series. It was produced by Universal Television and broadcast on NBC from 1969 to 1973. It was a wheel format series, an NBC programming approach also used by that network in series such as The Name of the Game and the NBC Mystery Movie.

The Price Is Right is a television game show franchise created by Bob Stewart, originally produced by Mark Goodson and Bill Todman; currently it is produced and owned by Fremantle.

Drew Carey has hosted the program since 2007.

In American broadcast programming, "burning off" is the custom of quickly airing the remaining episodes of a television program, usually one that has already been or is planned to be cancelled, without the intent to attract a large number of viewers. In addition to airing episodes two at a time, this process may also include rescheduling the show to a lower-rated time slot, or transferring the show to a less visible sister network. A low-rated show that premiered in the early portion of the regular television season may return during the summer, only to have the final episodes "burned off."

The WB was an American broadcast television network operated as a joint venture between the Warner Bros. Entertainment division of Time Warner and the Tribune Broadcasting subsidiary of the Tribune Company. Launched on January 11, 1995, it was one of two networks developed by major film and television studios in late 1993—alongside the United Paramount Network —to compete with Fox and the longer established Big Three television networks.
