I still remember the "Two all-beef patties, special sauce, lettuce, cheese, pickles, onions, on a sesame seed bun" jingle. And it was created in the 1970s.
All it does is describe what's in a Big Mac. But it's probably one of the best ad campaign jingles ever.
I have to say, I like ad campaigns that tell me what a product is or does or how it's better than its competitor, and what the price is. I loathe ad campaigns loaded with lots of atmosphere that don't tell me a darn thing.
