Which album received the 2000 special award for biggest one-week sales ever?

No Strings Attached received the 2000 special Billboard award for the biggest one-week album sales ever.

The album, released by the American boy band NSYNC, opened with approximately 2.4 million copies sold in the United States during its first week. That extraordinary debut established a new record for the largest single-week album sales total in the modern SoundScan era.

The success was driven by NSYNC’s enormous teen-pop following, heavy promotion and anticipation after the group’s earlier breakthrough. The album included hits such as “Bye Bye Bye” and “It’s Gonna Be Me,” helping it remain one of the defining pop releases of 2000.

The record was eventually surpassed by Adele’s 25 in 2015, which sold more than 3 million copies in its opening week. That later change does not alter the 2000 Billboard award: at the time, No Strings Attached held the record and was recognized for it.
