This Week I Learned has been published since mid-1995. In the beginning it was an email sent to a list of friends, who forwarded it on to their friends. A few years later we started accepting subscriptions and it started to grow. At one time the email list reached 40,000 subscribers and we were forced to place This Week on the Internet to take care of the great number of readers.
We have since expanded to 622,599 individual readers since 6 October 2005, when we begin seriously tracking our readers. In the last 26 days, we have had our heaviest concentration of readers from the following countries:
United States
