Social media has emerged as an influential force in China, where internet penetration is growing rapidly. Some key Chinese social media sites include Xiaonei, Wealink, and Tudou. Blogs and online forums known as BBSs are very popular, with over 40% of Chinese reporting reading blogs weekly. Blogs allow government officials and businesses to engage directly with consumers, but companies must navigate sensitivities and address issues that arise online carefully to avoid criticism spreading from the internet to mainstream media.
