3D Television

3D television (3DTV) is television that conveys depth perception to the viewer by employing techniques such as stereoscopic display, multi-view display, 2D-plus-depth, or any other form of 3D display.

Most modern 3D television sets use an active shutter 3D system or a polarised 3D system, and some are autostereoscopic without the need of glasses.

As of 2017, most 3D TV sets and services are no longer available.

Space Patrol

Space Patrol is an American science fiction adventure series set in the 30th century that was originally aimed at juvenile audiences via television, radio, and comic books.

It was broadcast on ABC from March 1950 to February 1955. It soon developed a sizable adult audience, and by 1954 the programme consistently ranked in the top 10 shows broadcast on a Saturday.

The stories followed the 30th-century adventures of Commander-in-Chief Buzz Corry (Ed Kemmer) of the United Planets Space Patrol and his young sidekick Cadet Happy (Lyn Osborn), as they faced interplanetary villains with diabolical schemes.

ABC

The American Broadcasting Company (ABC) is an American multinational commercial broadcast television network that serves as the flagship property of Walt Disney Television, a division of Disney General Entertainment Content of The Walt Disney Company.

The network is headquartered in Burbank, California, on Riverside Drive, directly across the street from Walt Disney Studios and adjacent to the Roy E. Disney Animation Building. The network’s secondary offices, and headquarters of its news division, are in New York City, at its broadcast centre at 77 West 66th Street on the Upper West Side of Manhattan.

Since 2007, when ABC Radio (also known as Cumulus Media Networks) was sold to Citadel Broadcasting, ABC has reduced its broadcasting operations almost exclusively to television. It is the fifth-oldest major broadcasting network in the world and the youngest of the American Big Three television networks. ABC is nicknamed “The Alphabet Network”, as its initialism also represents the first three letters of the English alphabet, in order.

ABC launched as a radio network in 1943, as the successor to the NBC Blue Network, which had been purchased by Edward J. Noble. It extended its operations to television in 1948, following in the footsteps of established broadcast networks CBS and NBC, and well as the lesser known DuMont. In the mid-1950s, ABC merged with United Paramount Theatres (UPT), a chain of movie theaters that formerly operated as a subsidiary of Paramount Pictures. Leonard Goldenson, who had been the head of UPT, made the new television network profitable by helping develop and greenlighting many successful series. In the 1980s, after purchasing an 80% interest in cable sports channel ESPN, the network’s corporate parent, American Broadcasting Companies, Inc., merged with Capital Cities Communications, owner of several print publications, and television and radio stations. Most of Capital Cities/ABC’s assets were purchased by Disney in 1995.

ABC has eight owned-and-operated and more than 230 affiliated television stations throughout the United States and its territories. Some ABC-affiliated stations can also be seen in Canada via pay-television providers, and certain other affiliates can also be received over-the-air in areas near the Canada–United States border. ABC News provides news and features content for select radio stations owned by Cumulus Media, as these stations are former ABC Radio properties.
