Kong Ming
Once upon a time, in a corner of China, there was a mythical group of phone testers called KONG MING.
Software teams would send their software to Kong Ming and Kong Ming would find timing errors and functional errors and feature errors and stability errors and generally test the sh*t out of your mobile phone software. You could even send them software and ask them to reproduce issues. By return you'd get a comprehensive bug report and the choice of improving your product quality.
(Not all teams improved their software..)
Then Nokia sold the whole lot to Microsoft, who fired them. The End.
