The dark side of Wikipedia: How founder Jimmy Wales indirectly profits from the online encyclopedia. Also on the show: Networking to fight homesickness - the German platform InterNations connects expats around the globe. And in Shift Exit: Creating art with flashlights - a trio from Cologne makes light painting videos.
Wikipedia is one of the most popular sites on the Internet. The online encyclopedia is so beloved because it's free -- and also completely free of advertising. Nonetheless, founder Jimmy Wales still profits from Wikipedia.
Wikipedia is considered an exemplary model of how to provide free access to knowledge. In Germany alone, about 7000 volunteers regularly write articles - without any pay. They feel they have a duty to the common good. The online encyclopedia is run by the non-profit Wikimedia Foundation. Once a year its founder Jimmy Wales collects donations to maintain and develop the technology involved in the Wikipedia website. But what Wales doesn't mention is that, with his platform Wikia, he indirectly earns money from Wikipedia's success.
People living abroad often have a hard time. In their new country of residence they're faced with many questions. How do they deal with red tape? Where can they find a good GP? On the InterNations platform, users help each other.
Expats, diplomats, members of aid organizations and engineers working overseas all have difficulty building up social contacts far from home. Many of them haven't much leisure time, so they use the Internet to compare notes on their new homes. This is the group InterNations is targeting. The networking platform works much like Facebook and now has 520,000 members around the world.
The German trio of artists known as Lichtfaktor does most of their work at night. Using long exposure times, they produce photographs on which they 'paint' magical and quirky pictures with the light from flashlights. Their animated video clips are produced painstakingly, frame by frame. In their video "Denizen", whales and sharks dance through their home town of Cologne.
