Linda Yaccarino, the new boss of troubled social media firm Twitter has started the role earlier than expected, officially replacing Elon Musk.
Ms Yaccarino, previously head of advertising at media giant NBCUniversal, immediately updated her LinkedIn profile with the new role.
Mr Musk has said he plans to remain involved with the firm.
She takes the helm on the same day Twitter snapped up another senior NBCUniversal executive Joe Benarroch.
Mr Benarroch also starts on Monday, focussing on business operations.
“I am looking forward to bringing my experience to Twitter, and to working with the entire team to build Twitter 2.0 together,” he said on Twitter.
On Twitter, Ms Yaccarino said: “Welcome to the flock @benarroch_joe! From one bird to the next.
In his last job Mr Benarroch was the executive vice president for communications, advertising and partnerships at NBCUniversal. Earlier in his career, he worked at social media giant Facebook.
Late last week, reports emerged that Twitter’s second head of trust and safety under owner Elon Musk had resigned.
Ella Irwin took the post when previous head Yoel Roth left in November 2022 – a month after Mr Musk took over the company.
The head of trust and safety is tasked with content moderation, a topic which has come under the spotlight since Mr Musk’s takeover of the firm.
The reason for Ms Irwin’s resignation is unclear. However, it came a day after Mr Musk publicly criticised a content moderation decision made at Twitter.
Since buying Twitter for $44bn (£35.4bn), Mr Musk had been under pressure to find someone else to lead the firm and refocus his attention on his other businesses, which include electric carmaker Tesla and rocket firm SpaceX.
Mr Musk named Ms Yaccarino as Twitter’s new chief executive last month. Ms Yaccarino started her post on 5 June, overseeing business operations at the platform, which has been struggling to make money.
That is a few weeks earlier than Mr Musk had originally said.
The world’s richest man said he would stay involved in the platform as executive chairman and chief technology officer.
