Decathlon is a French sporting goods retailer founded in 1976 in Lille, known for affordable own-brand gear for dozens of sports. Its short advertising jingle, built as a simple memorable sonic logo, has played for years in television spots, online videos and stores across Europe. Listeners saved it as a ringtone and shared it as son original, which helped it travel beyond advertising into meme edits and soundboards. Online, the sting now works as shorthand for sport, shopping and a successful purchase, even for viewers who have never visited a store.
