In a discussion on why Heinz has such high market share for ketchup in the Pittsburgh area, one commenter posts, "It's just better ketchup. Their other products may be closer in quality to the competition, but for Ketchup nobody compares. When you go to a restaurant and they have a different kind, it feels you are eating at some cheap cafeteria."
This is really telling, but probably not the in the way Matt intended.
Heinz doesn't make better ketchup. Heinz makes better Heinz ketchup. There's a huge difference.
If you define ketchup the way most people do, you define it as, "the ketchup I grew up with." Or to be more specific, "the ketchup my mom served me, the one that I was allowed to serve myself when I turned three…"
One thing that marketers do is sell us a feeling, not a set of molecules or bits. When you spend $3 on a bottle of ketchup, that's what you're buying. And Matt and the rest of us are so brainwashed we rationalize it as 'better ketchup.'
