Society of LondonTheatre president Mark Rubinstein said:
"I am delighted that for the ninth year running we are able to report year-on-year growth in ticket income for London Theatres.
"It is particularly astonishing that we are able to report increasing sales - of over half a billion pounds - for a year that we always knew would have exceptional challenges.
"Against the background of a tough economic climate, London theatre continues to buck the trend, offering dazzling, world-class entertainment, which has audiences from both home and abroad flocking to the West End to catch exciting new productions as well as much-loved long running favourites."
