USA Today reports that's the highest single-week sales total in a decade, since Eminem's The Eminem Show rang up 1.322 million in 2002.
Red set a single-week sales record at iTunes, where it sold 464,000 copies. At Target, which offered a version of Red that included a bonus CD containing six additional tracks, Swift sold more than 400,000 units -- the highest total for any album in the retailer's history.
Additionally, Red has sold more than 4.5 million individual downloads, led by 2.4 million-plus copies of single We Are Never Ever Getting Back Together.
Swift's 2010 Speak Now album sold 1.047 million in its first week and has gone on to move a total of 4.2 million units. Swift has sold more than 17 million albums since releasing her self-titled debut in 2006.
Since SoundScan began tabulating sales in 1991, Red is the 18th album to reach the seven-figure mark in a single week, and Swift becomes the only female act to accomplish the feat twice.
