November 1983 and featured 30 UK hit singles from that year on a double vinyl LP or cassette. Although the compilation of recent hit songs into a single release was not a new concept (K-tel and Ronco, for example, had been issuing various-artist compilations for some years), this was the first time that two major record labels had collaborated on such a venture. Virgin agreed to a deal with EMI, which allowed a greater number of major hits to be included (the first album in the series included a total of "eleven number ones" on its sleeve). The album went to number one, and soon after, CBS/WEA's The Hits Album adopted a similar format to Now!. The two series co-existed for the rest of the 1980s, and when Universal (formerly PolyGram from Now 8 in 1986 through to Now 42 in 1999) joined the collaboration, the Now! series was more successful commercially. The Out Now series by MCA and Chrysalis was also established as a rival to the series, but was short-lived and lasted only two volumes. By 1989, Now, Hits, and other various-artist compilation albums were occupying such a large fraction of the UK Albums Chart that a separate UK Compilation Chart was created to restrict the Albums Chart to releases by a single act. The rate of release settled very quickly to three per year: one release around late March/early April, another around late July and a third around late November. Over a hundred "main series" (not including spin-off and special edition) albums have been released to date. The UK series has followed a double-album format throughout the series (many other foreign franchises of the Now! series are only released on one disc), now exploiting the capacity of the CD to include between 40 and 46 tracks over two discs. Since November 2005 (Now That's What I Call Music! 62), the Now! series have only been released on CD and digital download formats. Previously, the series had been available on vinyl, cassette and MiniDisc, until these formats declined in popularity. Peter Duckworth and Steve Pritchard have been managing the Now! brand since NOW 17. Mark Goodier has voiced the Now! adverts since Now That's What I Call Music! 21 in 1992, when he worked for BBC Radio 1, with the exception of Now That's What I Call Music! 95 in 2016, which was voiced by Matt Edmondson due
