bmw drift camp / marco kalantari :
"My new film for BMW China has launched. This was a viral campaign, the idea was to make people in China believe that aliens have created crop circles in Qinghai province (Western China). Therefor we produced four short clips that looked like shot with iPhones, suggesting that several hikers have found those crop circles by coincidence and the posted the videos online. Those videos were placed on several social websites and Chinese versions of youtube. The story exploded, dozens of sites in China and abroad reported about the alien landing in Qinghai. Then BMW put the main film online on China's most popular blog site weibo (www.weibo.com/bmwchina) and revealed the cheat.
Within the first 12 hours 80.000 people shared this story with their friends, over 7000 comments were posted. In seven days the film passed the mark of 2 million views."
