“1989,” which required only two months to register as 2014’s best-selling album,
crossed the 4 million mark after only 12 weeks of release. The fastest to achieve the milestone since Usher’s “Confessions,” the album reached 4 million at a rate unrivaled by any of Swift’s previous four albums.
Sophomore album “Fearless,” which was previously her fastest-moving release,
needed 50 weeks to reach 4 million. Third and fourth albums
“Speak Now” and “Red” each needed 69 weeks to get to four million, while Swift’s
self-titled debut achieved the milestone after 125 frames.
