Apple did the "App Store".

It reminds me of the Crayon story. Seems simple: wax drawing tool. But wooo! Crayola had to give up the name.

Personally, it's a tough call. They are all Crayons, they are all App Stores. Not sure what the solution is.

Wikipedia claims the word Crayon goes back to the 1600s, and has photos of boxes with the word "crayon" from 20 years before the company that became "Crayola" existed.

So what name did they have to give up?

IT'S CALLED AN APPLICATION STORE, NOT AN APP STORE.
