Is there a commercial application of Genetic Programming?

Hi there,

While this seems interesting feeld, I was not able to find a
commercial program that use it and gives real benifits from it. I
consider timetabling and job shop
scheduling problem to be GA and they are good examples for application
of genetic algorithms. But despite of some (scientific or not)
experiments in GP is there any real usage of them in the real world,
now?

Regards
