'Mamma Mia!' breaks U.K. DVD record

More than 5 mil discs sold, fueled by Christmas period

LONDON -- Universal's "Mamma Mia!" has become the biggest-selling DVD of all time in the U.K., after huge sales over the Christmas period.

The DVD was already the fastest-selling U.K. DVD of all time, shifting 3.1 million units in its first week on sale, according to the Official Charts Co.

It tops the year-end sales chart with total sales of 5.005 million, according to the OCC, which means it has also overtaken Disney's "Pirates of the Caribbean: The Curse of the Black Pearl" at the top of the all-time sales list. "The Curse of the Black Pearl" has sold 4.7 million units to date.

The OCC estimates that one in four British households now owns a "Mamma Mia!" DVD.

The movie soundtrack, released in the U.K. by Polydor, was the biggest selling U.K. compilation of 2008, selling more than 1 million copies. The success also saw three other ABBA-linked albums sell more than 100,000 copies in 2008: ABBA's "Gold -- Greatest Hits" (Polydor) and "18 Hits" (Polar) compilations and the London stage recording of the "Mamma Mia!" musical, also on Polydor.
