PopTech seems very similar to the TEDtalks, but with more of a focus on technology and social networking. They describe themselves as "a unique innovation network – a global community of cutting-edge leaders, thinkers, and doers from many different disciplines, who come together to explore the social impact of new technologies, the forces of change shaping our future, and new approaches to solving the world’s most significant challenges. We are known for our thriving community of thought-leaders, breakthrough innovation programs, visionary annual conferences and deep media and storytelling capabilities." Videos are arranged in categories; many deal with sustainable technologies and energy sources.
