(the initiatives on this timeline reflect the objective reality of crowdsourcing, and will not be biased by this appartenance to eYeka).;xNLx;;xNLx;In order to make it as complete as possible, you're eagerly invited to contribute by submitting crowdsourcing initiatives that have been missed.

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
