Little LP (1961 – 1975)

The Little LP (also known as a Jukebox EP) was a 7-inch vinyl record with up to three songs on each side, that played at 33 ⅓ rpm in stereo, and had a small centre hole. They were first introduced by Cadence Records in late 1961, though the Cadence version was in mono and was not designed for jukeboxes.

The Little LP was not successful in the retail market, but it was picked up by Seeburg for use in their new jukebox, introduced in September 1962. The Seeburg version of the Little LP was in stereo, came with title strips, and had a colour cover for display in the jukebox. A number of record companies signed up, mostly easy listening and classical labels, and by 1963 there were 233 titles available with over 1,000 by 1966. Little LPs were also made for other jukebox manufacturers such as Wurlitzer and ATI.

Little LPs were essentially cut-down versions of the full 12-inch LP, and shared the same artwork. Record companies saw the potential of promoting the full LP version by having a selection of tracks available to hear, and the cover on display, in places where adult listeners gathered.

However by 1969, output of Little LPs had dropped sharply. A couple of small manufacturers revived the format in the early 1970s, but only a few titles per year were released in the period 1970-1975. Seeburg introduced new jukeboxes that didn’t play Little LPs in 1971, and the introduction of quadraphonic Little LPs didn’t make any difference as there were very few quadraphonic jukeboxes to play them on.

There were no new titles on the Little LP format for jukeboxes in 1976, but a few Little LPs have been released for the retail market as specialty items since then.

Open reel instrumentation and data logging tape (1949 – 2000s)

Magnetic tape was first used for data logging and instrumentation recording in 1949, when Jack Mullins installed modified Ampex Model 300s at Point Mugu Naval Air Station and at Edwards Air Force Base, both in southern California.

Tape has been heavily used since then for military, industrial, government and research applications. The Inter-Range Instrumentation Group (IRIG) set the standards for instrumentation tape recorders.

Instrumentation recorders were built to much more stringent standards than other tape recorders, and recorders that used direct, FM and PCM recording have been available.

On ¼-inch wide tape, there are typically 4 tracks, whereas on ½-inch tape there were 7, or sometimes even 14, tracks. On 1-inch tape, there were 14 or 28 tracks. Tape is usually wound on the reel with the recording surface facing towards the hub (the opposite of audio tape). Metal NAB reels were often used, for reels between 10.5 and 16-inches, but 7-inch plastic reels with cine spindle hubs have also been used.

Instrumentation recorders also used tape in cassette form, including systems that recorded onto S-VHS tape, and the Digital Instrumentation Recorder from Sony that used the SD1 cassette.

Instrumentation and data logging systems now use hard disks or flash memory for storage.

White label vinyl record (1948 – )

White label vinyl records are generally 12-inch LPs, or 7-inch singles and come with a plain centre label (usually white) and are in plain packaging. The centre label might have handwritten details of the artist and title, or may be rubber stamped, or have a sticker applied.

Some white label records are test pressings made by the pressing plant, usually in quantities of 5 or less,  and then listened to to check the sound quality before pressing larger runs.

Some white label records are produced for promotional purposes, including advance copies sent to retailers or to DJs. Sometimes white labels are used to conceal artist identities, so the record is listened to without prejudice. Dance music producers might produce white label copies to play in dance clubs to gauge crowd response.

Other white label records are unofficial or partially unofficial releases, for example if a remix was made without the consent of the artist or label.

Generally, white label records are not distributed to the general public.

Grundig Stenorette (1954 – 1970s)

The Stenorette was an office dictation machine introduced by Grundig in 1954, and successfully sold internationally. It was perhaps the earliest magnetic tape dictation system – at the time of its introduction, most office dictation systems were using discs or belts onto which grooves were pressed, such as the SoundScriber, Audograph, or Dictabelt systems. The first model, the Stenorette A, was nicknamed the ‘tree frog’ due to its green colour. Like some other dictation systems, the microphone doubled as the speaker, and contained stop/start controls.

The Stenorette cassette contained a single reel of ¼-inch tape, and a loop on the end was pulled out and clipped into the take-up reel. Recording time was 30 minutes per cassette, but some offered 45 minutes. Some tapes, particularly those from the US, seem to have no cover and are simply a small reel.

The Stenorette cassette system lasted into the 1970s with the introduction of the Stenorette SL model in 1972, but Grundig launched its first machine using its new cassette format, the Steno-Cassette in the same year. The Steno-Cassette was a true cassette containing dual reels and as well as being more compact, didn’t need to be rewound before being removed from the machine. The Stenorette name was continued on machines using the newer Steno-Cassette format.

LP (Long Play) 12 inch record (1948 – )

The LP (Long Play) record is an audio format for phonograph records, introduced by Columbia Records in 1948 and still in use today.

LP records are made of vinyl (either virgin or recycled) and together with a playing speed of 33⅓ rpm and the use of microgrooves, allow for a playing time of around 45 minutes. Previously, 78 rpm records had a playing time of just around 3-4 minutes per side, so an ‘album’ of records was sold as a set, and this name continued to describe a collection of songs on a single disc.

Each side of an LP contains a single continuous groove, with an average length of 460 m.

LP records are generally 12 inches in diameter, but 10 inch LPs have also been produced at different times. The amount of vinyl in an LP is generally 130 g, but some records were produced with less (sometimes as little as 90 g). Modern high-fidelity LPs tend to use more, such as 180 g. Generally LPs are pressed on black vinyl, but coloured vinyl and picture discs (with a card sandwiched between two clear sides of vinyl) have been produced, as have shaped vinyl and even neon vinyl.

By as early as 1952, LPs represented 16.7% of unit sales, rising to 24.4% in 1958 (by then, most of the remainder was 45 rpm singles, 78 rpm only representing 2.1%).

Stereo sound was introduced in 1958, and quadraphonic records were sold in the 1970s for a time.

The LP had no serious competitors for long-playing recordings until the 1970s when the Compact Cassette improved in quality, and then in the 1980s with the introduction of the Compact Disc. LPs ceased to be a mainstream format in the early 1990s, but continue to be produced in small but increasing numbers.

35mm film (1892 – )

35mm film was the most common film gauge for cinematography, and was also used in still photography (in the form of 135 film).

The name derives from the width of the film strip. When used for motion pictures, the image is across the film and each frame usually has four perforations giving 16 frames per foot, whereas when used for photography the image is lengthways along the film and each frame uses eight perforations. In conventional motion picture film, the image is 22 x 16mm (known as the ‘Academy ratio’). The shape and frequency of the perforations differed in the early years.

The 35mm format was introduced in 1892, soon after the introduction of transparent flexible film in 1889,  at a time when a large range of different film gauges were in use. By 1909 it became accepted as the international standard gauge and remained so until largely replaced by digital cinematography. Although other gauges have been used for cinematography, 35mm remained the most popular with professional film makers as it provided a good trade-off between cost and image quality.

Until the 1950s, 35mm film was made of cellulose nitrate which was highly inflammable and difficult to extinguish once alight. It was replaced with ‘safety film’ (cellulose triacetate). From the 1990s, film stock was made with a synthetic polyester safety base.

Sound was introduced around 1926, with Warner Bros. using synchronised phonograph discs. Later sound-on-film systems include optical analogue, optical digital, and magnetic strips. DTS soundtracks use a timecode printed on the film to synchronise with Compact Discs.

Between 2005 and 2015, most cinemas rapidly converted to digital projection, and in 2014 Paramount Pictures announced that it would no longer supply 35mm prints of movies in the US. Whilst 35mm film is still in use for both shooting and showing movies, it is rapidly becoming a niche format.

Cigarette card (1875 – early 2000s)

Cigarette cards were a particular form of trade card, initially popularised by tobacco companies as a way of selling their products, and after World War II were also used by some other manufacturers such as tea companies.

Card was used as a stiffener in paper packs of cigarettes, and beginning in 1875 in the US, these cards began to carry images, for example of actresses, sportsmen or Native American chiefs. In 1878 they also began to include information about the image on the back of the card.

In 1887, W.D. & H.O. Wills began to issue cigarette cards in the UK.

The range of images expanded over time and began to be issued in colour, and the cards became popular as a way of viewing and collecting exotic images from around the world. They also began to be issued in sets, and around 1900 albums began to be produced to enable people to collect and store the cards together.

In 1939, cigarette card production virtually ceased in the UK as paper was in short supply during the war. After the war, ‘cigarette’ cards were issued by tea companies such as Brooke Bond in the UK, who issued cards until 1999. There have been some cigarette cards issued since, such as by the US tobacco company R.J. Reynolds Tobacco Company who issued several series through a couple of its brand in the early 2000s.

Not all types of cigarette cards are the same size, but the standard size was around 67 x 36mm.

7-inch EP (1952 – )

The 7-inch EP (for Extended Play) was a format introduced in 1952 by RCA Victor, just a few years after the introduction of the 7-inch single format in 1949.  It sat between the 7-inch single and the 12-inch Long Play (LP) record, and like the 7-inch single it span at 45 rpm so could be played on any photograph with a 45 rpm setting.

By using narrower grooves, it was possible to squeeze 7½ minutes of playing time on each side at the expense of volume, allowing more than one song on each side (generally EPs have between three and six tracks). Like LPs, EPs did not necessarily have ‘title’ tracks, and could have different names to the songs on them (for example the 1963 Beatles EP simply called ‘The Beatles’ Hits’).  They were also packaged more like an LP with a cardboard picture sleeve, whereas 7-inch singles until the 1970s generally had paper sleeves with just the record label on them.

Whilst less common in the US, the 7-inch EP was widely sold in the UK and some other European countries, and between 1960 and 1967 they were popular enough for Record Retailer magazine in the UK to compile a separate EP chart. They were a good way for artists to produce something more substantial than a single between LP releases.

They declined in popularity after the 1960s, and faced competition from formats such as 10-inch and 12-inch singles or EPs (which could allow for more sound volume with wider grooves), as well as Cassette and CD singles or EPs. However, small numbers of 7-inch EPs are still released.

Dictaphone Dictet (1957 – early 1960s)

The Dictaphone Dictet was a portable dictation device introduced by the Dictaphone Corporation in 1957. It was perhaps the earliest portable magnetic tape dictation system – the Grundig Stenorette was an office dictation system using tape, introduced in 1954. An earlier portable system, the Protona Minifon used wire recording.

The Dictet was fully transistorised and weighed 1.2kg. The cassette had a metal shell and could record up to 60 minutes (30 minutes per side) on ¼-inch tape that ran at 2½ inches per second. Using special mercury batteries, the Dictet could operate for 20 hours.

The Dictet lasted until at least 1962, but it is unclear how much longer it lasted against newer competitors such as the Compact Cassette of 1963.

Philips EL 3581 (1958 – early 1960s)

The Philips EL 3851 was an office dictation machine introduced by Philips (known as Norelco in the US) in 1958 and was one of the earliest magnetic tape dictation systems (the Dictaphone Dictet was launched shortly before it). At the time of its introduction, most dictation systems were using discs or belts onto which grooves were pressed, such as the Dictabelt, SoundScriber and Audograph systems.

Although the EL 3851 uses a cartridge so no threading is required, the tape is housed on two separate 3-inch reels with ¼-inch tape and cine spindle holes suitable for domestic open reel tape recorders. Removing a clip from the cartridge shell allows the reels to be removed.

Like some other dictation machines, the microphone also doubles as a speaker, and contains some tape controls. A foot pedal and external speaker were also available.

Philips later introduced the much smaller Compact Cassette format in 1963, followed by the mini-cassette in 1967 and it doesn’t appear the EL 3851 was produced for long.
