YouTube, the Google-owned video sharing website, has become a major platform around the world for news, posing challenges to media organisations. Citing the Pew Research Center report, it said that news related events were the most searched items on YouTube in five months of a 15-month period in 2011 and early 2012. That means that news is rapidly becoming important on the site, which is popularly known for amateur videos of children and pets. (AFP)
