The news that mainstream media organisations use Twitter as a broadcast channel is hardly surprising.

The study of Twitter feeds from 13 major news outlets in the US by the Pew Research Center’s Project in Excellence in Journalism is in line with earlier academic studies.

The Pew study, in collaboration with the George Washington University’s School of Media and Public Affairs, found that Twitter was mainly used to distribute news and boost traffic to a news outlet’s website.

Just over 90 per cent of the tweets analysed during a week provided a link to a news story on the organisation’s own website.

Twitter was used far less as a reporting tool or as a way to filter information. Just two per cent of tweets asked for information or for eye-witness accounts. A minute one per cent of tweets were retweets from outside a news outlet.

There was a slight variation when it came to the Twitter feeds of individual journalists, rather than institutional accounts.

A study of the accounts of 13 individual journalists found that three per cent of tweets asked for information and six per cent were retweets of material not sourced from their news outlet.

Pew concludes:

“These findings reveal limited use of the institution’s public Twitter identity, one that generally takes less advantage of the interactive and reportorial nature of the Twitter.

This behavior resembles the early days of the web. Initially, news organizations, worried about losing audience, rarely linked to content outside their own web domain. Now, the idea is that being a service – of providing users with what they are looking for even if it comes from someone else – carries more weight.”

Admittedly, Pew only studied a small sample. But other research has also highlighted how news outlets have tended to use social media to try to reach a broader audience, rather than engaging in an exchange with the audience.

A study by Marcus Messner, Maureen Linke, and Asriel Eford (PDF) found that the official Twitter accounts of the top newspaper and TV outlets in the US functioned largely as an automated RSS feed of the latest news stories.

Another study found that many newsrooms automatically generated a tweet  (PDF) with a link when a story was published on the website.

The use of Twitter and other social networking tools to go beyond broadcast is still the exception in newsrooms. Yet there is potential for so much more.

In a chapter on Twitter for the new second edition of The Routledge Companion to News and Journalism, I explore how newsrooms are adopting and adapting to social media, concluding:

Twitter is affecting how news organisations respond to breaking news, how journalists go about their reporting and whose voices are heard. New journalistic genres are emerging as news outlets incorporate social media services into daily routines. A process of negotiation is taking place, as traditional ways of working bump up against social, cultural and technological practices that disrupt established journalistic norms.

The Pew study analysed one week of tweets on the main Twitter feed of 13 different news organisations, amounting to more than 3,600 tweets.
