NBC Cancels the US adaptation of WDYTYA

NBC has chosen not to renew the television series: Who Do You Think You Are? after it's third season.

From Ancestry.com:

We want to thank NBC for their support of this terrific series, which over the last three years has inspired many viewers to follow their passion to learn more about who they are and where they come from," said Tim Sullivan, President and CEO of Ancestry.com. "We have a great partnership with the show's producers, Is or Isn't Entertainment and Shed Media, and we look forward to exploring other avenues of distribution.

It's important to note that Ancestry implies they as well as the show's producers are interested in finding another  "avenue of distribution," - that is, another network willing to air the show.  So this might not be the end of WDYTYA in America.  Of course, it definitely isn't the end of WDYTYA. The original British show, and the Australian adaptation both seem to be active, if not other adaptations as well.
