In 2008, Microsoft attempted to validate the experiment by analyzing the minimum chain length it would take to connect 180 billion different pairs of users in the Microsoft Messenger database.

In 2016, researchers at Facebook reported that the social networking site had reduced the chain length of its members to three and a half degrees of separation.
