“Mentor” a buzzword?

I am hearing "mentor" everywhere. The government wants to give immigrants a mentor in order to integrate them in Denmark. The newspapers business section recommends leaders to get a mentor. Television has a show with people presenting there inventions and ideas to a board of mentors. Is it a buzz or are we just starting to see the potential of others experience. It makes sense, let me find one of my own so this protege can develop herself.
