BBC trials Instagram news service for 15-second bulletins

The BBC is trialling a new Instagram news service, Instafax, to deliver 15-second news bulletins.

Helen Lewis, deputy editor of the New Statesman, explained that a fragment of news is "always more interesting" than a longer piece, but worried that it can leave viewers with a "shallow" knowledge of the subject.

John Crace, creator of the Guardian's Digested Read, urged the BBC presenters taking part to maintain their "verve" during the reduced bulletins.

First broadcast on BBC Radio 4's Today programme on Monday 10 February.
