Film Strips
The filmstrip is a form of still image instructional Media (communication), media, once widely used by educators in primary and secondary schools (K–12) and for corporate presentations (e.g., sales training and new product introductions). It was largely made obsolete by the late 1980s by newer and increasingly lower-cost full-motion videocassettes and later on by DVDs. From the 1920s to the 1980s, filmstrips provided an easy and less expensive alternative to full motion educational films, requiring little storage space and being very quick to rewind for the next use. Filmstrips were durable and rarely needed splicing. They are still used in some areas. Technology A filmstrip is a spool of 35mm movie film, 35 mm positive film containing a series of images (often thirty-two to sixty-four) in sequential order. Filmstrips could be inserted either vertically or horizontally, depending on the manufacturer, in front of the projector aperture. With vertically oriented strips, t ...

Gramophone Record
A phonograph record (also known as a gramophone record, especially in British English) or a vinyl record (for later varieties only) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on a phonograph (or "gramophone", "turntable", or "record player"). Records have been produced in different formats with playing times ranging from a few minutes to around 30 minutes per side. For about half a century, the discs were commonly made from shellac and these records typically ran at a rotational speed of 78 rpm, giving it the nickname "78s" ("seventy-eights"). After the 1940s, "vinyl" records made from polyvinyl chloride (PVC) became standard replacing the old 78s and remain so to this day; they have since been produced in various sizes and speeds, most commonly 7-inch discs pla ...

Full Motion Video
Full-motion video (FMV) is a video game narration technique that relies upon pre-recorded video files (rather than Sprite (computer graphics), sprites, vector graphics, vectors, or 3D models) to display action in the game. While many games feature FMVs as a way to present information during cutscenes, games that are primarily presented through FMVs are referred to as full-motion video games or interactive movies. Recent full motion video games often combine the use of CGI/green screens and in-game graphics for immersion. The early 1980s saw almost exclusive use of the LaserDisc for FMV games. Many arcade games used the technology but it was ultimately considered to be a fad and fell out of use. In the early 1990s FMV games had a resurgence of interest, the proliferation of optical discs gave rise to a slew of original FMV-based computer games such as ''Night Trap'' (1992), ''The 7th Guest'' (1993), ''Voyeur (video game), Voyeur'' (1993), ''Phantasmagoria (video game), Phan ...

Video Cassette Recorder
A videocassette recorder (VCR) or video recorder is an electromechanical device that records analog audio and analog video from broadcast television or other AV sources and can play back the recording after rewinding. The use of a VCR to record a television program to play back at a more convenient time is commonly referred to as '' time shifting''. VCRs can also play back prerecorded tapes, which were widely available for purchase and rental starting in the 80s and 90s, most popularly in the VHS videocassette format. Blank tapes were sold to make recordings. VCRs declined in popularity during the 2000s and in 2016, Funai Electric, the last remaining manufacturer, ceased production. History Early machines and formats The history of the videocassette recorder follows the history of videotape recording in general. Ampex introduced the quadruplex videotape professional broadcast standard format with its Ampex VRX-1000 in 1956. It became the world's first commerciall ...

Show'N Tell
The Show 'N Tell is a toy combination record player and filmstrip viewer manufactured by General Electric from October 1964 to the 1970s at GE's Utica, NY facility. It resembles a television set, but has a record player on the top. Records and slides were sold for it in combination (known as Picturesound programs). The slide strips, a flat plastic key 11 inches long containing a strip of 16mm color film, are inserted into the top of the device. As the record played (typically telling a story), the slide strip, through which the images were projected on the screen, automatically advance to illustrate it. The mechanism by which the slide advanced is purely mechanical, and was based on the rotation of the turntable, so proper operation required manually spinning it a few revolutions before beginning the presentation. The original selling price of the unit was $29.95 and Picturesound programs sold for 99 cents with "a library of five programs" selling for $4.95. Thirty-five pro ...

8-track Tape
The 8-track tape (formally Stereo 8; commonly called eight-track cartridge, eight-track tape, and eight-track) is a magnetic-tape sound recording technology that was popular from the mid-1960s until the early 1980s, when the compact cassette, which pre-dated the 8-track system, surpassed it in popularity for pre-recorded music. The format was commonly used in cars and was most popular in the United States and Canada and, to a lesser extent, in the United Kingdom, Ireland and Japan. One advantage of the 8-track tape cartridge was that it could play continuously in an endless loop, and did not have to be ejected, turned around and reinserted to play the entire tape. After about 80 minutes of playing time, the tape would start again at the beginning. Because of the loop, there is no rewind. The only options the user has are play, fast forward, record, and program (track) change.

Subaudible Tone
A subaudible tone is a tone that is used to trigger an automated event at a radio station. A subaudible tone is audible; however, it is usually at a low level that is not noticeable to the average listener at normal volumes. It is a form of in-band signaling. Overview These tones are included in the audible main portion of audio in the case of the satellite; on tape, these often are filtered. Typically, subaudible tones are at one of the following frequencies: 25, 35, 50, 75 hertz (Hz), or combinations of those frequencies. Until computerized radio automation became inexpensive and common, 25 and 35 Hz were used either in the audio stream or, in the case of tape cartridges used in radio broadcasting (better known as " carts"), on a special track on the tape to indicate to a radio station's automation system that it was time to trigger another event. With the advent of computers and digital satellites, these tones are relegated to triggering commercial announcements a ...

Hertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or Cycle per second, cycle) per second. The hertz is an SI derived unit whose formal expression in terms of SI base units is 1/s or s−1, meaning that one hertz is one per second or the Inverse second, reciprocal of one second. It is used only in the case of periodic events. It is named after Heinrich Hertz, Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. For high frequencies, the unit is commonly expressed in metric prefix, multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. T ...
