8 mm movies are a motion picture film format with a film strip that is 8 millimeters wide. There are two principal versions: standard 8 mm film (also known as "regular" or "Double") and Super 8, which has smaller and more widely spaced perforations, allowing for a larger image area.

Compared to larger film formats, 8 mm movie film was relatively inexpensive to purchase and develop. It thus became a popular format for "home movies", and so many people have films of family history interest in this format that they want transcribed into some more modern digital format.

The availability of projection equipment in many homes also made this one of the first formats heavily used for retail sales of commercial movies, including short features, cartoons, and (especially) pornography. The "8 mm porn loop" was an early commercial success via direct sales to consumers as well as via exhibition in (sometimes coin-operated) "peep show" adult theaters.

The film strip was an instructional multimedia format commonly used in schools from the 1940s to the 1980s. A filmstrip is a spooled roll of 35 mm positive film with images arranged in sequential order. The frame size is smaller than normal 35 mm film, such that two image frames of a filmstrip take up the same amount of space as a single 35mm frame.

Film strips were designed for use with simultaneous audio recordings. These audio recordings would include tones or signals used (either manually by the film strip projector operator or electronically by the projector itself) to indicate when the next image on the film strip should be projected.

:''Not to be confused with [[ZIP]], an unrelated compressed file format.''

The Zip disk is a rotating magnetic storage medium housed in a hard plastic protective cassette. This "super-floppy" disk storage product came in 100 MB, 250 MB, and 750 MB capacities, and was sold from 1994 through approximately 2003.

ARC (compression format)

2012-10-28T19:10:33Z

Bacchus: clarity edits and some links

ARC was for a time (1985-89) the leading file archiving and file compression format in the [http://en.wikipedia.org/wiki/Bulletin_board_system BBS] world, replacing the formats used by earlier utilities which generally only did one of the two functions (either combining multiple files in one file for convenient download, or shortening the file length to take less download time and disk space). Combining the two functions in one utility simplified the process of preparing files for download and extracting them at the other end, leading to a rapid rise in popularity for the utility (also called ARC) and format both.

However, the ARC format suffered an equally rapid decline in its popularity after the company that published the [http://cd.textfiles.com/rbbsv3n1/atnu/arc51.exe ARC utility] (called System Enhancement Associates or SEA, run by Thom Henderson who was very active in FidoNet) brought a successful trademark and copyright suit against rival Phil Katz, whose PKARC and PKXARC utilities were compatible with the ARC file format. The lawsuit was widely regarded by the BBS community as being a "David vs. Goliath" case of a faceless corporation bullying a "little guy", though in fact both companies were small, home-based operations. Nevertheless, the fallout from the suit led to rapid adoption of the competing [[ZIP]] format, introduced by Katz in 1989, and ARC files are no longer commonly encountered.

The fact that archives from an early period of BBSing are often in this format encourages bad puns referring to those who trawl such old archives as "Raiders of the lost ARC."

There are, unfortunately, also several other incompatible file formats that have been used over the years with an "ARC" designation or file extension, so it's possible that a data set that is purportedly of type "ARC" is not actually of this format.

== Identifiers ==
* File extension: '''.ARC'''
* MIME type (Internet media type): Has no specific registered type; generic binary '''application/octet-stream''' is generally used, or perhaps unregistered custom types with an '''x-''' prefix
* Uniform Type Identifier (Apple): '''public.archive.arc'''

Exposed and developed photographic film may be encountered as a file format either in negative -- a color-reversed state from which prints may be produced on [[photographic paper]] -- or as a transparency that can be viewed directly (with the naked eye, or more typically, with backlighting and magnification) or projected with a projector. The primary identification of photographic film formats is by size.

Photographic film is encountered in still formats (typically, a single image) and movie formats (strips of film transparencies with numerous sequential images designed for the projection of moving pictures). Some movie formats designed for exhibition also encode audio data (soundtracks) on film alongside the sequential images. Other movie formats were intended for exhibition with simultaneous audio provided by a synchronized separate recording.

The stereocard (also called stereo card, stereograph card, [http://en.wikipedia.org/wiki/Stereogram stereogram], or stereo view) is a pair of photographic prints mounted on card stock and viewed through a [http://en.wikipedia.org/wiki/Stereoscope stereoscope] to produce a three dimensional image. Stereocards were in popular use from the 1880s through the 1930s.
