YOC stands for "Your Opinion Counts" and was founded by Dirk Kraus in 2001 with a spectacular campaign called "Cash or Crash". Around 80,000 mobile phone users decided by text message whether a Porsche 911, which had been hanging from a crane at Potsdamer Platz in Berlin for days, was going to crash to the ground or given away in a prize draw. YOC was one of the first providers of mobile advertising in Germany, which at this time consisted mainly of text message competitions. Coca-Cola and Pepsi were some of YOCs first customers. In 2004 one of the first MMS campaigns in Germany was implemented on behalf of the sports clothing manufacturer Nike. For the event series "Panna K.O.", 25,000 football-loving community members were invited to watch the football fun-events. In the following years YOC developed into a market leader for mobile advertising and expanded throughout Europe.
