I just read this on /. :

July 22, 1999 

       To All Licensees, Distributors of Any Version of BSD: 

       As you know, certain of the Berkeley Software Distribution ("BSD")
source code files require that further distributions of products containing
all or portions of the software, acknowledge within their advertising
materials that such products contain software developed by UC Berkeley and
its contributors. 

       Specifically, the provision reads: 

        * 3. All advertising materials mentioning features or use of this
software * must display the following acknowledgement: * This product
includes software developed by the University of * California, Berkeley and
its contributors. 

       Effective immediately, licensees and distributors are no longer
required to include the acknowledgement within advertising materials.
Accordingly, the foregoing paragraph of those BSD Unix files containing it
is hereby deleted in its entirety. 

       William Hoskins
       Director, Office of Technology Licensing
       University of California, Berkeley "

Does this at all affect us end-user-type folks who don't write software?
