'Worst Aquarium Ever' Review Leads to Merch Sales Surge at Whaling Museum

The New Bedford Whaling Museum in Massachusetts is cashing in on a viral bad review.

The Google review was left by a disappointed guest back in 2020 who called the whaling museum the "worst aquarium ever," leaving just one star. …. the marketing department couldn't let the blistering review go, turning it into a product line, including shirts and tote bags.

In just one week, the museum's sales soared 250% due to the viral merch.

A museum is cashing in after a one-star Google review calling it the "worst aquarium ever" became an unexpected viral hit.
The New Bedford Whaling Museum in Massachusetts, which highlights the history, science and art of whaling rather than marine animals, embraced the one-star review by boldly printing the phrase on T-shirts, sweatshirts and tote bags.
"A few weeks ago, we added to the ‘Worst Aquarium Ever’ merchandise line with a new crew neck T-shirt and tote bags," Amanda McMullen, president & CEO of New Bedford Whaling Museum, told Fox News Digital.
"Since July 20, we have had more than 2,400 orders from all over the globe."
"It's honestly a great museum," a user commented. "I love that it's gone viral because it's just a wonderful place to support."
McMullen said she's thrilled. "We are filling orders so quickly that hundreds of boxes and packages are heading out every day," she said.
"We’ve gotten to know our postal carriers very well," she added.

I’ll definitely have to visit and while I’m there, stock up on gift garb. A tad pricey, I suppose, but the proceeds are going to the museum, not Sam Walton’s heirs, so no whining from me.
