The BBC has launched a new video news service via social media site Instagram.

Instafax, named after the BBC’s now defunct Ceefax service, is hoped to help BBC News break into the mobile and tablet market.

The service delivers news pieces in the form of 15-second videos to make the site concise and uniform.

Steve Herrmann, head of BBC News Online, said: "We want the process to be organic, and we’re keen to trial new ideas on how we can use our video content to reach new audiences.

"James Harding [director of BBC News] has been clear in his vision to find innovative ways to bring the best of our journalism to new audiences, something our team has been looking at for some time."

The new service already has over 7,000 followers and comes as BBC News mobile traffic exceeded desktop traffic for the first time.

The brief videos are elaborated by supporting text, but there is currently no hyperlink functionality, limiting the information available from the service.
