Tumblr partnered with Twilio and Mobile Commons to create a click-to-call campaign against SOPA and PROTECT IP laws, which aimed to raise awareness about the potential dangers of these bills. The campaign was successful, with over 87,000 calls made to representatives and nearly 1,300 hours spent talking to lawmakers. Tumblr's CEO, David Karp, credited the campaign's success to the urgency of the situation, the power of social media rallying, and the impact of Twilio's click-to-call capabilities. The partnership between Tumblr, Mobile Commons, and Twilio showcased the potential for technology companies to use their platforms to drive direct political action and promote important issues.
