Though the West End does not report figures for individual shows, the 2013 box-office figures across the board published by the Society of London Theatre show an increase in all genres. Attendance at musicals increased by 3 percent to 8,198,290 admissions, earning a 10 percent increase in revenue of £355,354,832. Attendance at plays also increased by 3 percent to 4,248,258 admissions, earning a 12 percent increase in revenues of £140,020,830. Attendance at the remainder of performances – for opera, dance, performance and entertainment – increased by 12 percent to 2,140,728, earning a 9 percent increase in revenues of £90,130,793.

In a press statement, Mark Rubinstein, president of the Society of London Theatre commented, "I am delighted that we can announce a record year for London theatre attendances as well as a tenth year running of year-on-year growth in ticket income. These figures pay testament to the quality, vibrancy and enduring popularity of the London stage, which, despite a difficult economic climate, continues to pull in the crowds thanks to the world-class entertainment on offer and inclusive pricing structures. With the combined Box Office advance sales also reaching new heights in December, we are looking forward to another year of success stories for our theatres in 2014."

According to press materials, the increase in revenue can be largely attributed to a markedly improved 72.7 percent seat capacity achieved across the year and strong advance sales up by an average of 21 percent, peaking at over £70 million in December. New musicals that included The Book of Mormon, Charlie and the Chocolate Factory, Once and The Commitments boosted sales on musicals, while plays also registered a strong year, with the Michael Grandage Company's inaugural resident season at the Noel Coward previously reporting 93 percent attendance.

Also on the plays front, there was a sell-out run for Helen Mirren in The Audience.
