McDonald's Teenie Beanie Baby Happy Meals
Chaos: Significant, with collectors showing up and demanding Beanie Babies as soon as a new Happy Meal launched
New Yorker/New York Times coverage: None, but we have Wall Street Journal with "Teenie Beanie Babies Generate Big Buzz, Thrilling McDonald's." Someone who worked at McDonald's during the Beanie Baby boom reminded me of the frenzy that accompanied Teenie Beanie Baby drops when I was sought suggestions for out-of-control menu item launches on Twitter.
Happy Meals, accompanied by limited-time Teenie Beanie Babies, would swiftly sell out as Beanie Baby fanatics rushed to the chain at 10:30 am, when McDonald's began selling lunch. The partnership between McDonald's and Beanie Babies continued until the Beanie bubble burst around the turn of the millennium.
Popeyes' Chicken Sandwich
Chaos: Workers were being threatened by hungry customers as chicken sandwiches sold out
By far the biggest menu item launch of 2019, Popeyes chicken sandwich exploded on the scene thanks to a Twitter battle with Chick-fil-A. The chain's social media war for the title of best chicken sandwich kicked off endless debate — and sent thousands of people to Popeyes.
Workers were exhausted and ready to quit, as restaurants quickly ran out of sandwiches. Supply which was supposed to last two months sold out in just two weeks.
KFC's Double Down
Chaos: Significant, though the buzz surpassed sales
New Yorker/New York Times coverage: The Times' food critic Sam Sifton reviewed the menu item, stalked by the "geek paparazzi" at Eater. His verdict: "a slimy and unnaturally moist thing, with flavor ginned up in a lab." America lost its mind when KFC rolled out a menu item that sandwiches cheese and bacon between two pieces of fried chicken. "This is deep-fried madness," Colbert Report host Stephen Colbert said of the sandwich when it launched. "This is breaded insanity. It is a sandwich that lacks all sandwich-ness. It's like an edible Hieronymus Bosch painting wrapped in a paper straitjacket. If a sandwich has no buns, can it truly be called a sandwich?"
The Unicorn Frappuccino was one of the first major made-for-Instagram menu items to break into the mainstream. To this day, Starbucks executives say it was the "most viral" drink launch of all time.
The color-changing Frappuccino, which was only supposed to be available for four days, was also a nightmare for workers to make.
Fortunately, most stores sold out in just a day or two. "We ran out of unicorn frappuccino ingredients after the first day....we sold 508 unicorn f----- frappuccinos in ONE F------ DAY!" one barista wrote.
McDonald's Szechuan Sauce
Chaos: People were rioting in parking lots
New Yorker/New York Times coverage: Things got so bad, The Times had to write up the outrage. Fans of the cartoon "Rick and Morty" spent most of 2017 trying to force McDonald's to bring back Szechuan McNugget sauce.
When McDonald's obliged, with a "really, really limited" rollout of the sauce at a handful of locations, customers were furious at the limited supply.
In Wellington, Florida, police were called to one location.
In New York City, crowds of angry customers formed. McDonald's eventually brought the sauce back to all locations.
The Doritos Locos Taco was so successful it essentially fueled Taco Bell's turnaround when it launched in 2012. The chain sold more than a billion Doritos Locos Tacos in the first year, hiring an estimated 15,000 workers to keep up with demand. "The idea sounds really simple, but it has to deliver on two fronts: the classic Taco Bell taste and the distinctive Doritos experience," Taco Bell product developer Steven Gomez told Business Insider. "Unlike a tortilla chip, taco shells can't break, and have to properly hold the taco ingredients."
