Twitter Names Marketing Chief

(RTTNews) - Microblogging website Twitter Inc. (TWTR) on Tuesday announced the appointment of former American Express executive Leslie Berland as its Chief Marketing Officer.

Fittingly, Twitter CEO Jack Dorsey announced the new hiring through a tweet: "Welcoming @leslieberland to Twitter! She will join as our CMO to help tell the stories of our iconic product!"

Berland added her own tweet, thanking her new boss and expressing excitment for her new position: "Thanks @Jack! Excited to join you and the amazing teams to bring to life the power, uniqueness and magic of Twitter!"

Berland will be responsible for Twitter's global consumer, product and sales marketing, according to reports. She will take over the job from CFO Anthony Noto, who had also been serving as interim CMO.

Berland had joined AmEx in 2005, media reports said. Her most recent job there was as executive vice president of global advertising, marketing and digital partnerships at American Express.

Twitter is in the middle of an executive shake up. On Monday, Dorsey announced that four top executives are leaving the company, including engineering chief Alex Roetter, product head Kevin Weil, human-resources vice president Skip Schipper and media head Katie Stanton.
