NEW YORK/DENVER (Billboard) – In the days following Michael Jackson’s June 25 death, fans flocked to record stores and digital music outlets to purchase one last memory. And merchants say they expect the Jackson sales surge to last for weeks — maybe even months.

“With the around-the-clock coverage and questions about his death, this story will keep going, with every development giving it a new bit of life,” says Kerry Fly, vice president of purchasing and marketing at wholesaler Eurpac.

Jackson’s solo album sales in the United States skyrocketed from 10,000 copies in the week before his death to 422,000 in the week ended June 28, according to Nielsen SoundScan.

During the same period, U.S. track downloads surged from about 48,000 copies to 2.6 million. The week of his death, the best-selling track was “Thriller” at 167,000 copies, and the top-selling album was “Number Ones” at 108,000.

In the United Kingdom, Jackson held 11 of the top 200 album positions and 43 of the top 200 singles based on sales monitored by the Official Charts Co. for the week ended June 27. Despite the inclusion of only two full days of sales after Jackson’s death, “Number Ones” topped the OCC album chart after selling 46,400 physical copies and 10,000 downloads. “Thriller” also reached the top 10 for album at No. 7, with combined physical and digital sales of 14,900.
