IBM, Sears (far more dominant in retail in its day than Amazon is today), General Motors (hi Toyota), US Steel (hi foreign steel), Pan-Am (hyper powerful at its peak), Alcoa (anti-trust + foreign competition), and a dozen others that were every bit as powerful as Amazon at their peak.
Oh and Walmart is slowly being replaced by Amazon. Walmart is/was the most dominant retailer in world history.
The rise and fall of major corporations isn't necessarily the result of the inexorable application of market forces. Alcoa's grasp on the market was broken as much by the aftermath of 'war socialism' as anything else, for example. Companies compete with each other on legal, regulatory, and social planes as well as in the marketplace.
I think it's difficult to find any single X that makes "if a company is bad at X, it will be replaced by competitors" a consistently true statement, without X being essentially synonymous with "succeeding".
