QT famously had a dual, "non-commercial" and "commercial" licenses, before they switched to LGPL.

Highcharts.js has a free-for-noncommercial, paid-otherwise license system

gSOAP has a separate commercial use license. They use a mix of GPLv2 plus a separate license for companies that want to avoid having to relicense their own products under the GPL (as a consequence of the viral nature of GPL vs something like LGPL).
As far as I see, popular licenses are: 1. Commercial source 2. Open source - copy left eg. GPL 3. Open source - liberal, do whatever you like eg. MIT
which are just handful, when software is eating the world ;)
