Check the visual below for a timeline of social media from 2004 to 2014, which includes some recent usage stats, and comes courtesy of MediaVision. While the roots of social media can be found in Friendster and Myspace, it’s probably fair to say that social didn’t really start to change the world until Facebook launched in 2004. YouTube (2005) and Twitter (2006) debuted shortly thereafter, and from here we never looked back. Within a decade of Facebook, Tumblr, Pinterest, Google+, Instagram and Snapchat all made grand entrances onto the scene. Today, using social media as a business marketing tool has become essential for brands of all shapes and sizes, in almost every industry across the world.
