The Boston-based company offered users a 9/11-themed promotion that required three New York-based teams — the Yankees, Mets and Jets — to win their games Monday, the 22nd anniversary of the attacks on the World Trade Center and Pentagon and the downing of a passenger jet in a field in Pennsylvania.

After an outcry on social media from people offended by the promotion titled “Never Forget,” DraftKings took it down and apologized.

“We sincerely apologize for the featured parlay that was shared briefly in commemoration of 9/11,” the company wrote. “We respect the significance of this day for our country and especially for the families of those who were directly affected.”

[The answer to the question “Too soon?” will always be “yes” when it comes to merchandising 9/11. In fact, it’s too soon for “Pearl Harbor” merchandising too. It’s surprising that anyone needs to be told that. — Ed]
