Two poorly reviewed star vehicles were the next-highest-grossing plays: “China Doll,” with Al Pacino ($12.6 million), and “Misery,” with Bruce Willis ($12.5 million); plays without stars did much less well. Of the $1.373 billion grossed on Broadway last season, 13 percent went to plays.

“I continue to be really worried about the plays,” said Victoria Bailey, executive director of Theater Development Fund, the organization that runs the TKTS booths. “When people are going to the theater, either as a tourist or for a celebratory event, they tend to go to musicals, and so I think it’s even harder for plays to make a go of it. In the short run, we’re holding even, but what is five years from now going to look like?”

Charlotte St. Martin, the president of the Broadway League, attributed the industry’s continued growth to tourism (about 67 percent of the Broadway audience comes from beyond New York City and its suburbs) and to the mix of offerings during a season of unusually diverse programming.

Tourism has grown in New York for six years in a row — this year there are expected to be 59.7 million visitors to the city, according to Fred Dixon, the president of NYC & Company, the city’s official tourism agency. Although Broadway’s growth rate this past season was lower than it had been the previous season, Ms. St. Martin said she was pleased.

“We have more million-dollar-a-week shows, and more shows with strong attendance, than we used to,” she said. “We’ve become a much bigger part of pop culture, with ‘Glee’ and ‘Smash’ and live television shows like ‘The Sound of Music’ and ‘The Wiz,’ and more people are aware that Broadway isn’t just something for the 1-percenter.”

Nonetheless, there are reasons for concern. For the first time since the Broadway League began releasing records, the average ticket price actually declined, albeit only slightly, to $103.11, from $104.18. That might be good news for consumers, many of whom complain about the high cost of tickets to shows at the 40 large theaters in and around Times Square that make up Broadway, but it is worrisome for producers, whose costs for mounting and marketing shows seem to grow ever larger.

There are other indicators that the industry’s success is enjoyed by a relative few. Including long-running hits, short-lived holdovers from the previous season, and new shows, there were 72 productions on Broadway last season — 41 musicals, 28 plays, two magic shows and one dance spectacle. About half of all the grosses were earned by just 10 of those productions. And, as is true every season, a vast majority of new productions flopped.
