NBC Teletext was a teletext service provided by the American TV network NBC from 1981 to 1985, based on the NABTS standard. [1] [2] [3] [4]

Initial trials started in Los Angeles in 1981. [5] Transmissions started as a regular service on May 16, 1983 [6] after FCC approval, [7] [8] [9] in parallel with CBS similar ExtraVision [10] service.

Initially, the NBC Teletext was composed of a 50-page magazine, with the index page listing the following topics: Newsfront, Weather, Sports, Money, People, Your Body, Living, Your Stars, On the Soaps, Fun & Games, Kid's Korner, Partners, Credits. [9] Graphics were reasonably detailed, allowing a detailed rendition of weather maps or movie posters. [9]

Since teletext provides real-time updates, it was expected that the service would attract advertisers like airlines, stores or businesses interested in constantly updating their rates and schedules. [11] As there were no available standalone consumer decoders on the market, it was hoped that by launching the system manufacturers would soon built teletext capability into all television sets. [6] [11]

Demonstrations of the system were performed at the 1983 National Association of Broadcasters convention in Las Vegas, the Organization of Iberian-American Broadcasters (OTI) in Mexico City, and the International Television Symposium and Technical Exhibition in Montreux. [12] [1] [13] Special content was developed for these demonstrations.

In 1984 projections, NBC expected the teletext service to be profitable by 1987 and reach 10 percent of US homes by 1990. [11]

These expectations were not met, and the system was shut down in January 1985. [14] [15]

Closed captioning (CC) is a form of subtitling, a process of displaying text on a television, video screen, or other visual display to provide additional or interpretive information, where the viewer is given the choice of whether the text is displayed. Closed captions are typically used as a transcription of the audio portion of a program as it occurs, sometimes including descriptions of non-speech elements. Other uses have included providing a textual alternative language translation of a presentation's primary audio language that is usually burned-in to the video and unselectable.

NAPLPS is a graphics language for use originally with videotex and teletext services. NAPLPS was developed from the Telidon system developed in Canada, with a small number of additions from AT&T Corporation. The basics of NAPLPS were later used as the basis for several other microcomputer-based graphics systems.

Color television or colour television is a television transmission technology that includes color information for the picture, so the video image can be displayed in color on the television set. It improves on the monochrome or black-and-white television technology, which displays the image in shades of gray (grayscale). Television broadcasting stations and networks in most parts of the world upgraded from black-and-white to color transmission between the 1960s and the 1980s. The invention of color television standards was an important part of the history and technology of television.

<span class="mw-page-title-main">Teletext</span> Television information retrieval service developed in the United Kingdom in the early 1970s

Teletext, or broadcast teletext, is a standard for displaying text and rudimentary graphics on suitably equipped television sets. Teletext sends data in the broadcast signal, hidden in the invisible vertical blanking interval area at the top and bottom of the screen. The teletext decoder in the television buffers this information as a series of "pages", each given a number. The user can display chosen pages using their remote control. In broad terms, it can be considered as Videotex, a system for the delivery of information to a user in a computer-like format, typically displayed on a television or a dumb terminal, but that designation is usually reserved for systems that provide bi-directional communication, such as Prestel or Minitel.

Electra was a teletext service in the United States that was in operation from 1982 up until 1993, when it was shut down due to a lack of funding, and discontinuation of teletext-capable television sets by the only US television manufacturer offering teletext capability at the time, Zenith. It was owned, operated and maintained by Cincinnati-based Taft Broadcasting and Tulsa, Oklahoma-based Satellite Syndicated Systems (SSS), later known as Tempo Enterprises, in cooperation with cable/satellite TV station Superstation WTBS, who carried Electra's data on their vertical blanking interval. SSS's own TV network, the Satellite Program Network, carried the service before it was shut down in 1989. The service was also available to C-band satellite dish users via the Galaxy 1 and Satcom 3R satellites.

ExtraVision was a teletext service created and operated by the American television network CBS in the early to mid-1980s. It was carried in the vertical blanking interval of the video from local affiliate stations of the CBS network. It featured CBS program information, news, sports, weather, even subtitling for CBS programming. ExtraVision could also have its pages customized by the local affiliate station carrying it, for such things as program schedules, local community announcements, and station promotions. WGBH Boston, a pioneer in assisting the deaf and hard-of-hearing with closed captioning, also provided content for those audiences to ExtraVision and assisted in providing captioning for CBS programming via ExtraVision.

ON TV was an American subscription television (STV) service that operated in eight markets between 1977 and 1985. Originally established by National Subscription Television, a joint venture of Oak Industries and Chartwell Communications, ON TV was part of a new breed of STV operations that broadcast premium programming—including movies, sporting events, and concerts—over an encrypted signal on a UHF television station and leased decoders to subscribing customers. At its peak in 1982, ON TV boasted more than 700,000 customers—more than half of them in Los Angeles, its most successful market. However, the rapidly expanding availability of cable television, coupled with a recession, caused the business to quickly lose subscribers at the same time that Oak Industries was experiencing severe financial difficulties. Between March 1983 and June 1985, all eight operations closed.
