Music Box Ltd. was a television production company that developed from a pioneering pan-European 24-hour cable and satellite channel that ran from March 1984 to the 30th of January 1987, originally created by Virgin Vision, one of Richard Branson's business ventures launched in 1983.

As a 24-hour TV channel in the 80s, Music Box was able to reach 60 million potential viewers in Europe and the Middle East thanks to satellite distribution. At the time, a satellite reception system was very expensive and for this reason the channel was very big in countries where cable TV was largely used, such as the United Kingdom, The Netherlands, Belgium, Germany and Scandinavian countries. Music Box was also partially retransmitted on several terrestrial local channels in Italy and a special Italian version of Music Box was created in spring of 1988. A couple of Music Box shows were also retransmitted by Japanese broadcaster NHK. In 1986, Yorkshire Television from ITV decided to go 24 hours a day, but little cash was invested in that service, and so, most of the downtime was filled with a rebroadcast of Music Box. It was the first time that an ITV company (allegedly) broadcast 24 hours. Music Box was originally based in the heart of London, in a building where Virgin Vision and Super Channel were also based, and later gave home to the London offices of CNN International and Cartoon Network. The address during the satellite years was 19-21 Rathbone Place (London) and the public address for Music Box was P.O. Box 4DX, London W1A 4DX, England.

On the 30th of January 1987 Super Channel is launched on the same satellite frequency previously used by Music Box on pan-European satellite Eutelsat 1-F1 located at 13° east, replaced during 1987 by Eutelsat 1-F4. For this reason Music Box stops being a 24-hour TV channel and Virgin sets up Music Box as an independent producer of music programmes, continuing broadcasting its shows until the end of September 1987 for 10 hours a day on Super Channel. From October 1987 til January 1990 it reduced from 10 hours a day to just a couple of hours a day of music shows to be produced for Super Channel, with a two-month long break in late 1988 due to problems related with Super Channel, which was going to be sold. Music Box ended its satellite experience in January of 1990 with the last pan-European showing of "The Power Hour".

Directors on the channel include people like Rod Fairweather, John Leach, Les Harris, Ludo Graham, Simon Sanders and Siubhan Richmond.

After leaving satellite television, Music Box became a specialized producer of music shows for major British broadcasters and is now owned by Tinopolis, which also owns the Sunset+Vine firm, previously owner of Music Box. The company's best known show of this period is the late night ITV production Forever which features pop videos and interview clips from stock footage.
