On April 7 1994, "Kevin Bacon is the Center of the Universe"
The trivia game Six Degrees of Kevin Bacon is based on the concept of the small world phenomenon and rests on the assumption that any actor can be linked through his or her film roles to actor Kevin Bacon
In 2007, Bacon started a charitable organization named SixDegrees.org.
Every Actor has a Bacon Number!
Scientists and mathematicians have been calculating their Erdös number for years. Paul Erdös was the Kevin Bacon of mathematicians, having published more than 1400 papers with numerous collaborators. Anyone who was a co-author with Erdös has an Erdös number of one. Their collaborators, in turn, have an Erdös number of two, and so on. The network of mathematicians is a small-world network. It works because papers have multiple authors. Other fields work the same way, and a 2001 paper by Mark Newman shows that the collaboration networks of biomedical scientists, physicists, and computer scientists are also small world networks. The average distance between two biomedical researchers, according to his paper, is 4.6 – larger than that for actors, but still smaller than the mythical 6.

So It is closer to 7
In a research paper from June 2007,
Eric Horvitz of Microsoft Research and Jure Leskovec of Carnegie Mellon University analyzed 30 billion conversations among 240 million people using Microsoft Instant Messenger in June 2006. It turned out that the average path length, or degree of separation, among the anonymized users probed was:

It is not good enough to deploy SWE’s.They have to have a low degree of separation to our users to be relevant.
