It's not often you can cover a story from your desk almost as well as you could if you were on the ground. But social media and networking sites meant the most powerful images from the student protest were broadcast online before they hit television screens. As students and onlookers filmed scenes on their mobile phones it was websites like Flickr and YouTube that provided some of the most memorable footage. Asif Khan, who was working in the 30 Millbank building, took his mobile phone to the reception and filmed the moment protesters smashed through the windows with batons. There were no other cameras inside the tower and his footage was used by broadcasters around the world.
