Singles would often top the chart as a result of exposure in popular media, including films such as "Fifty Shades of Grey", "The Dark Knight Rises" and "Man of Steel". In July 2012, a rendition of "Spem in alium" by the Tallis Scholars topped the chart following its usage in "Fifty Shades of Grey". E. L. James, author of the original novel on which the film was based, said that she was delighted that her readers had been introduced to the piece of music, and that it was a "deserved number one". Three weeks later, the London Symphony Orchestra reached number one after their version of "Chariots of Fire" by Vangelis was used in the 2012 Summer Olympics opening ceremony. Three of the top five singles on that week's chart were related to the 2012 Summer Olympics.
