Buoyed by a rising stream of tourists, the unexpected popularity of an adolescent with Asperger’s syndrome, the star power of Larry David and Helen Mirren, and the enduring appeal of a lion named Simba, the Broadway season that just ended was the highest-grossing ever.

The Broadway League, a trade organization that represents producers, said on Tuesday that the 40 Broadway theaters had sold a record $1.365 billion worth of tickets in the year that ended Sunday.

Although the grosses are not inflation-adjusted, and although part of Broadway’s financial success is thanks to premium pricing for prime seats, the League said that Broadway also broke a record for attendance, drawing more than 13 million people. Attendance at Broadway shows has risen 13.3 percent over the last two years, the League said.

Several factors contributed to the growth, theater and tourism industry officials say: a boom in overall visits to New York City, a relatively healthy economy, a perception that Times Square is safer and more family-friendly than it had been, and a diversity of theatrical offerings.
