The BBC broke news this week when they said reporters are not allowed to break news via Twitter.

More than 2 years after the CBC declared an ‘online first’ mandate for their newsroom and after many other are flocking to the social networks to promote their stories, newscasts, and provide real-time updates to stories as they happen, the BBC is turning back the clock – sort of.

“When they have some breaking news, an exclusive or any kind of urgent update on a story, they must get written copy into our newsroom system as quickly as possible, so that it can be seen and shared by everyone – both the news desks which deploy our staff and resources (like TV trucks) as well as television, radio and online production teams.”
