Twitter: Linda Yaccarino outlines her plans for the social media firm

The new boss of social media firm Twitter, Linda Yaccarino, has outlined her plans for "Twitter 2.0.", after taking over from Elon Musk a week ago.

She says the company is "on a mission to become the world's most accurate real-time information source".

Since Mr Musk bought Twitter last year, it has faced criticism over its approach to tackling disinformation.

In a series of tweets, which was also emailed to employees, Ms Yaccarino echoed Mr Musk's goal, that Twitter must transform the "global town square".

She said this would help "drive civilisation forward through the unfiltered exchange of information and open dialogue about the things that matter most to us."

Mr Musk, who is a self-described "free speech absolutist", has criticised Twitter's policies on moderating content, arguing that it needed to be a genuine forum for free speech.

But his moves to reinstate right-wing accounts, whose views he has shared, and loosen moderation have driven away advertisers. In December, revenue reportedly fell by 40% to a year ealier.

Since buying Twitter last year for $44bn (£35.1bn), Mr Musk had been under pressure to find someone to lead the firm so that he could focus on his other businesses, which include electric carmaker Tesla and rocket firm SpaceX.

Ms Yaccarino is credited with helping to steer media giant NBCUniversal through upheaval in the industry caused by changing technology.

In her former role, she overhauled the company's advertising sales business and was behind the 2020 launch of its advert-supported streaming platform Peacock.

She now oversees business operations at Twitter, which has been struggling to make money, while Mr Musk continues as the company's executive chairman and chief technology officer.
