They were the first to market, though. That's my point. Being the first is a small advantage that can be lost for a ton of reasons, most of which don't require gross mismanagement.

And Bell's telephony network (which unlike consumer devices has a moat) was split up by the courts. I'm talking about telephones. Those devices with a base station, a handle, and a dial pad or a rotor (or sans all that, a switching board lady who will connect you to whomever you need to talk to).

Bell was the first to market with the personal telephone, but for some reason, didn't corner the market for consumer devices.
