A 1997 ad for Cheerios. This includes the song, "Did You Know".
Yeah, they didn't mention many numbers, but they did mention many persuasive facts such as, "low in fat", "low in sugar", "number 1 with kids", and "moms love them too". These remarks are supposed to make the viewer think that since it's healthy, kids love them, and it's mom-reccomended, that they should buy the product (Cheerios).
