McDonald's is one of the world's most recognisable fast food chains, founded in the United States in 1940 and known for restaurants and drive thru service worldwide. Its advertising jingles and in store beeps have become shorthand online for burgers, fries and takeaway food in general. Short clips taken from adverts, visits and parodies circulate on soundboards and in edited videos, where a few seconds are enough for viewers to identify the brand context. The sound remains popular because the association is immediate and works across languages and age groups.
