This timeline shows how the world's most valuable brands use crowdsourcing. It intends to become the reference place to gather and display information about brand-sponsored crowdsourcing initiatives.
This timeline has been created by [Yannig Roth](http://yannigroth.wordpress.com), PhD student at [Université Paris 1 Panthéon Sorbonne](http://www.univ-paris1.fr/ufr/ufr06/) and Research Fellow at [eYeka](http://www.eyeka.net/). In order to make it as complete as possible, you're eagerly invited to contribute by submitting crowdsourcing initiatives that have been missed.

Thank you!;xNLx;;xNLx;Contributors:;xNLx;- [Yannig Roth](http://yannigroth.wordpress.com) (curator);xNLx;;xNLx;Notes:;xNLx;;xNLx;Crowdsourcing is defined as the process of posting a problem online, having a vast number of individuals offering solutions to the problem, awarding the winning ideas with some form of a bounty, and using this input for innovation, marketing or communication ([Brabham, 2013](http://mitpress.mit.edu/books/crowdsourcing)).;xNLx;;xNLx;Among the various forms of crowdsourcing that exist, we limit the scope of this timeline to [creative crowdsourcing](http://yannigroth.wordpress.com/2012/07/07/defining-creative-crowdsourcing-crowdsourcing-of-creative-activities/) i.e. distributed creative problem-solving. This leaves aside micro-tasks, data-sourcing or voting initiatives, focusing on crowdsourcing were peoples' creative problem-solving skills are sollicited. ;xNLx;;xNLx;The most common forms of such initiatives are innovation tournaments, idea contests, creative competitions or branded web-platforms for idea generation. Finally, we have limited the events of this timeline to crowdsourcing initiated and leveraged directly by brands for their innovation or marketing strategies. Sponsored initiatives (such as the [Sony World Photography Awards](http://www.worldphoto.org/the-awards/), or the [Betacup Challenge](http://www.jovoto.com/blog/wp-content/uploads/2010/11/FINAL_Betacup-Release_June-17-2010.pdf)) have been left out.;xNLx;;xNLx;The world's most valuable brands are the 100 brands included in [Interbrand's Best Global Brands ranking](http://www.interbrand.com/en/best-global-brands/best-global-brands-2008/best-global-brands-2011.aspx). Our basis is the 2011 edition of the ranking, and the timeline will be updated with new entrants of the subsequent rankings.;xNLx;;xNLx;This timeline has been [released](http://news.eyeka.net/2012/09/how-the-worlds-best-brands-use-crowdsourcing-interactive-timeline/) on September 12th 2012
