The Yankees are, at the moment, a marketer’s dream. With a spirited start to the season, they can boast of having one of baseball’s best records, bask in the captivating presence of the Bunyanesque outfielder Aaron Judge and nod in approval at some popular changes to their ballpark — with all of these developments wrapped in the team’s rich history.

But even those selling points have yet to turn around attendance at Yankee Stadium, where ticket and suite revenues through last season had fallen by a staggering $166 million since the end of 2009, the year the Yankees christened the new ballpark with their last World Series title.

The financial figures, from the public filings the Yankees are required to make on their stadium bonds, represent a 42 percent loss in ticket and suite revenues over the last seven seasons. And despite the team’s compelling play this season, attendance through the first quarter of their home schedule is down from the same point last year.

The ticket and suite revenues are only a portion of the Yankees’ overall income, which also includes television and radio broadcast fees, advertising and licensing, and a portfolio of ancillary businesses. And indeed, the decline in ticket and suite income has offered some relief from baseball’s revenue-sharing system, allowing the Yankees to pay less into the pot that is distributed among all 30 teams.
