The BSD License

A liberal license that allows the source code to be used in proprietary applications, so long as the copyright statements remain in the source code. You do not have to make your source code available to others if you don't want to, unlike the GPL.

Earlier versions of the BSD License had an obnoxious advertising clause, which meant your documentation needed to say that it used BSD licensed code, but the current version of the license has dropped this restriction.

The MITLicense and the X11 license (and others) are very similar in spirit if not wording to the BSD one, but the BSD license is on a lot more software.
