Here’s How Companies Are Celebrating Star Wars Day by Tom Huddleston, Jr. @FortuneMagazine May 4, 2016, 12:55 PM EDT E-mail Tweet Facebook Linkedin Share icons “May the Fourth be with you!” That’s the pop culture pun greeting pretty much everyone with an Internet connection this morning, as the Star Wars reference (it sounds similar to the line “may the Force be with you” from the movies) has evolved in recent years from being an inside joke among fans to turning May 4 into an unofficial holiday. Originally a way for Star Wars fans to acknowledge one another along with their beloved movie franchise, the somewhat silly conceit eventually found its way (as all things holy do) into the hands of big brands and the people who man their social media feeds. The number of companies with Star Wars-related offers and advertisements seems to grow every year. And, of course, the Force is currently especially strong with the Star Wars brand after the franchise’s first new film in a decade, The Force Awakens, blasted its way to box office records after Walt Disney’s DIS Lucasfilm released it in December. And, Disney isn’t done making new Star Wars movies, with two more sequels planned in the coming years along with multiple spin-offs, including this December’s Rogue One. Countless companies and public figures looked to capitalize on Star Wars‘ soaring pop culture cache on Wednesday, ranging from the obvious (Lucasfilm itself) to the slightly more head-scratching (Gov. John Kasich, who just dropped out of the GOP presidential race). Even Campbell Soup CPB got in on the act, pitching its Star Wars-themed line of soups. Others participating in #StarWarsDay include Domino’s DPZ , Microsoft’s MSFT Bing, and Sony SNE . You could say the Force is with us. #MayThe4thBeWithYou pic.twitter.com/9LdiOydwC4 — Domino's Pizza (@dominos) May 4, 2016 Do or do not celebrate #StarWarsDay, there is no try.
