AllMusic (previously known as All Music Guide or AMG) is an online music guide service website. It was launched in 1991 by All Media Guide, which later became All Media Network.
AllMusic was launched in 1991 by Michael Erlewine of All Media Guide (later became All Media Network). The aim was to "[compile] discographic information on every artist who's made a record since Enrico Caruso gave the industry its first big boost". Its first reference book was published the following year.
The AMG consumer web properties AllMusic.com, AllMovie.com and AllGame.com were sold by Rovi in July 2013 to All Media Network, LLC. All Media Network, LLC was formed by the original founders of SideReel.com and Ackrell Capital.
The following are contributors to AllMusic, as of this date.
The content was initially published in book form in 1992 as the All Music Guide, and is now freely available to the public for online reference and information, as well as available via licensing for point-of-sale systems, media players, and online music stores.
All Media Network also produced the AllMusic guide series, which includes the AllMusic Guide to Rock, the All Music Guide to Jazz and the All Music Guide to the Blues. Vladimir Bogdanov is the president of the series.
In August 2007, PC Magazine included AllMusic in its "Top 100 Classic Websites" list.
