Nachos are delicious. Everybody knows that, and nobody questions it. Do you know what's better than nachos, though? Nachos with dips! Whether it's hot salsa, sour creme, guacamole or something else, all of us have a preferred nacho and dip combination. If you're in the business of selling nachos, your fastest route to a sale is reminding your audience how incredible the combination of nachos and dips can be - which is what Tostitos does with its logo.
Eagle-eyed nacho fans might have spotted this already, but if you look at the positioning of the two 'T's in the center of the word, they're enjoying a giant nacho between them. Below them, the dot of the 'I' is a huge bowl of (probably salsa) dip for the nacho to go in. When you see Tostitos, you think of nachos and dip - and now you know why!
