Change.org's 10 Biggest Victories as Petition Website Celebrates 100 Million Users

More than 100 million people have signed Change.org petitions to push for change on issues, the website has revealed.

The website launched in the U.K. in 2011 and now has more than eight million users here, making Britain its second largest market. A total of 3.3 million Britons have signed a petition whose goal was ultimately fulfilled. They included the largest change.org petition ever launched in the U.K.—which saw more than a million people signed it to "Save Meriam" from execution in Sudan for apostasy.

Ghoncheh Ghavami, a British-Iranian woman, was freed from jail in Iran after 777,000 people signed a petition calling for her release.
