In 2003, Peter Sheridan Dodds and his colleagues at Columbia University conducted a modern version of 6 degree of separation through studying e-mails on the Internet. They recruited over 60,000 participants from 166 different countries for the experiment. By factoring in the rate of dropouts, the researchers calculated a median chain length of between 5 to 7 people.
