I have to apologize for that. I suggested Fritos Chili Cheese Chips about ten years ago, several years after wishing to someone that I'd like chili cheese on french fries, and have been wondering when Frito-Lay would extend that flavor to potato chips.
They actually did so in 2011, or thereabouts. I haven't seen them in this area:

So that one goes to the waiting game with my very secretive family along with the rippled chip (1957, based on the corrugated layer in cardboard. I was 3 years old), the BBQ chip (1959. I was 5. I suggested using sweet hickory smoke BBQ sauce powder and adding yeast as a meat flavor substitute. How many others would think of yeast?), the onion chip. The garlic chip (5 again). When they failed, I thought to make it a dip flavor with sour cream powder.
The fried Crunchy Cheetos (1962. I was 8 ), The "cheesy Taco" Tortilla Chip (Nacho Doritos) and the tortilla chip (1966, though the company history states 1960 by an employee. They weren't sold until 1966, along with a no-cheese Taco Doritos chip),
Funyuns (loved onion rings), Bacon-Cheese Cheetos (short-lived; 1980's), Jumping Jack and Ranch Doritos, Sun Chips (multi-grain with Food Value), Limon Lays (Lime flavor), and Flaming Hots (a truth-or-dare line of snacks), and others that didn't make it.
That list is one of my 'coincidences'.
Currently I am wishing McDonalds would make a beef-onion gravied chili con carne and slap it on the Quarter Pounder. They tried a chiliburger before. It failed, but it wasn't classic beef-onion gravy-based chili.
I can say that because the folks know about that one, and because the Internet provides carbon dating, posts and dates...
