Sofa-lising with Newsnight
In 2010 the awful term "sofalising" was coined. It is communicating with friends online while lounging on the sofa rather than going out.
There is some data on it here.
This is really interesting territory for Newsnight, or #newsnight as we are known on Twitter. As our viewers pick up on, share and spread the debates introduced on the programme on Twitter, our hashtag can enter the UK trending lists.
This week's film about Alan Bennett's support to save local libraries from government cuts was just the latest example. Bennett reiterated his previously expressed belief that closing libraries constitutes child abuse - his views were then picked up on Twitter, resulting in his name appearing among the most cited phrases in the UK on the social media site after the programme.
This dual-screen media phenomenon is being driven by rapid changes in technology consumption. There has been 40% growth in mobile web use over the last 12 months, on smart phones especially, and all media organisations are predicting it will be a key growth area.
Good TV, especially for an organisation like the BBC, is often about being a space for collective audience experiences where communities can coalesce. And that's why our regular TV audience sat at home watching us on telly while tweeting about us from their laptops or mobiles is so important.
There has even been speculation that we sit in the programme gallery monitoring what is being said on social media and end interviews if someone is not going down well. For the record, we do not. Some nights we might find ourselves having no-one left to interview if we did.
There is an important caveat. Newsnight's social media audience is still a fraction of its television audience, and a fraction of the audience who consume our online content.
The numbers are still dwarfed by viewers who never mind tweeting from their smart phones, might have no internet access at all. So we need to be careful what we take from it but as raw data on what our audiences really think and react to immediately it is really useful.
The BBC is looking into how it can use second screens to complement what is happening on the dominant screen and how it can broaden the discovery, appeal and engagement with its audience by doing so. So watch this space... or should I say both spaces.
