New Twitter CEO Linda Yaccarino has explained why she took on the role in a Twitter thread and memo to employees. Yaccarino, formerly an advertising executive at NBCUniversal, said that Twitter, which she referred to as the "global town square", needed transformation.

She added that her major responsibility would be to rebuild Twitter's ads business, which has seen a relapse since Elon Musk's $44bn acquisition of the platform. Musk will oversee Twitter's product and engineering teams while Yaccarino leads everything else.
