A home movie is part of the motion picture filmmaking process made by amateurs, often for viewing by family and friends. When the hobby began, home movies were produced on photographic film, but accessibility of video production with video cameras and low cost data storage devices has made the making of home movies easier and more affordable to the average person. The boundaries between consumer movie-making and professional movie-making are becoming increasingly blurred as prosumer equipment often offers features previously only available on professional equipment.
In recent years, clips from home movies have been available to wider audiences through television series such as America's Funniest Home Videos, in Great Britain You've Been Framed! and Internet online video-sharing sites such as YouTube. The popularity of the Internet, and wider availability of high-speed connections has provided new ways of sharing home movies, such as video weblogs (vlogs), and video podcasts.
Development of film formats suitable for amateur hobbyists began early in the history of cinematography. For example, the 17.5 mm "Birtac" format was patented by Birt Acres in 1898. This format split the standard 35 mm film into two strips half as wide and was able to be loaded into the camera in daylight. Since the frames were also half the height of 35 mm frames, the Birtac format used only 25% of the amount of film stock used by 35 mm. Since the camera doubled as a printer and projector, equipment costs were also reduced.
Safety film and the 16 mm film format 
Another breakthrough in making film practical for home users was the introduction of safety film in the 1920s. Earlier "nitrate film" required special handling and storage, even after it was exposed and developed, since it is extremely flammable and has even been known to spontaneously catch fire as it gets older.
Many competing film formats were introduced in the early decades until 16 mm safety film was introduced by Eastman Kodak in 1923 and became a standard in the non-professional market. Although 16 mm had the advantage of users not being tied to one equipment manufacturer and there were obvious cost advantages compared to standard 35 mm, it was never able to eliminate smaller formats and it eventually was relegated to professional users, particularly in the education market.
8 mm film format and color 
In 1932, Kodak introduced another new format, 8 mm (now known as "Regular 8" or "Straight 8"), by slitting 16 mm film in half, again reducing by 75% the amount of film stock used per frame. This was the point at which home movies finally came within reach of the average family, and the smaller format allowed for much smaller and more portable cameras and projectors.
The introduction of Kodachrome color reversal film for 16 mm in 1935, and for 8 mm in 1936, facilitated home color cinematography. The availability of reversal film (Kodachrome was not the first) was very important to the home movie-making market, since it avoided the expense of separate negatives and positive prints.
Super 8 and Single-8 film formats 
Although developments in fine-grained film made Regular 8 mm film practical, it was largely superseded shortly after Kodak's 1965 introduction of Super 8 film. The Super 8 format used the same film width as Regular 8, but the perforations were smaller, allowing for a larger frame size yielding frames with less grain. In addition, Super 8 film came in cartridges for easier loading into the camera. A competing format from Fujifilm (Single-8) was also introduced in 1965 and used similar film, but in a different type of cartridge.
Home video-making 
The introduction of the Beta VCR in 1975 and VHS in 1976 heralded a revolution in the making of home movies. Videocassettes were extremely inexpensive compared to film and they could even be erased. This had the effect of greatly increasing the hours of footage of most family video libraries. It took a few years before consumer video cameras and portable VCRs were introduced, and later combined to create camcorders, but by that time, many consumers already had the playback equipment in their homes.
Omnipresence and controversy 
Portability and small size of digital home movie equipment, such as camera phones and PDAs with video capabilities, has led to the banning of such devices from various places, due to privacy and security concerns.
Pornographic movies of celebrities have been rumoured to exist for many years, but the ease of creating home movies on video has resulted in several celebrity sex tapes becoming available to the public, often without the permission of participants. The honeymoon video of Pamela Anderson and Tommy Lee from 1998 was the first highly publicized example.
Portability of digital equipment helps fuel other controversies as well, such as the incident on November 17, 2006 in which comedian Michael Richards got into a racist war of words with an audience member during his comedy club act. Large parts of the incident were captured on the camera phone of another audience member and broadcast widely.
Home movies have played important roles in controversial police investigations, a prime example being the Zapruder film of the 1963 assassination of U.S. President John F. Kennedy shot using an 8 mm home movie camera on Kodachrome II 8 mm safety film. This film was published and broadcast extensively and became official evidence for the Warren Commission, which was established on November 29, 1963 to investigate the assassination that had taken place exactly a week earlier.
