Activate is the Guardian's platform for innovators working across all sectors who are using the internet and its associated technologies to change the world. 

On 3 May 2012 some of the world's most influential and inspirational figures will once again descend on NYC's Paley Media Centre to discuss and debate the critical issues and strategies driving a more connected, creative and cohesive planet.

They'll be examining the influence of web technologies on areas as diverse as global media and finance, the environment, citizenship and access, democracy, government and accountability, education, the developing world, society, health and humanity.

Understanding how and why web technologies are reshaping almost every aspect of society poses one of the biggest questions and offers one of the greatest opportunities of our time.

Who should attend?

Senior level delegates from across private, public and third sectors, from the biggest media and technology companies, government organisations and international charities to the brightest technology start ups and VC investors. Made up of an eclectic mix of disciplines and sectors, previous Activate attendees include:
