On November 6, 2007, "Billboard" announced that even though The Eagles's first-week sales of "Long Road Out of Eden" had handily surpassed Spears, they would not debut atop the chart because of rules forbidding albums exclusively sold at one retail outlet (Walmart in this case) from entering the "Billboard" 200. The magazine's senior analyst and director of charts Geoff Mayfield explained he was frustrated by the situation, saying: "I can believe the Eagles sold more, but I'm not seeing anything that verifies for me that they outsold her and anything we see otherwise might be from people with a stake in suggesting that." During the afternoon of the same day, Walmart issued a press release announcing that "Long Road Out of Eden" had sold 711,000 copies. At night, it was announced through an article on "Billboard.biz" that after an agreement with Nielsen SoundScan, "Billboard" would allow exclusive album titles that were only available through one retailer to appear on the charts, effective that same week. Hence "Long Road Out of Eden" would top the "Billboard" 200, while "Blackout" would debut at number two, with sales of 290,000 copies. It became Spears' first studio album not to debut at number one. The album, however, set the record as the best-selling digital album debut by a female artist in a week at the time. Following the release of "Circus" in December 2008, "Blackout" re-entered the chart at number one-hundred-and-ninety-eight, with sales of 4,600 copies. As of March 2015, the album had been certified Platinum in the United States for shipments of 1 Million copies. platinum by the Recording Industry Association of America (RIAA).
