X certainly marks the spot.

The TEDx program was launched in 2009 to bring the mission of spreading ideas to the local level, with independent organizers curating their own events for their own communities. This week, the program is celebrating many milestones. Not only did yesterday mark the 5,000th TEDx event — this week also brings the 20,000th TEDxTalk.

So which of these many talks has proved the most popular? From baby geniuses and an 11-year-old food activist to the secret of living to 100, we have counted our views from TED.com and Youtube to bring you our 20 most-watched TEDx talks to date.
