U.S. record-buyers snapped up more than 1.25 million copies of the Beatles' "1" (Capitol) compilation in the days leading up to Christmas, easily making it the best-selling album of the week, according to industry reports.

Better than 4.5 million copies of "1" have sold in the U.S. during its first six weeks of release. The album--which also tops the U.K. charts this week--so far has spent four weeks at No. 1.
