Twitter has announced that it is expanding its ad presence on iOS and Android phones. This update will allow Promoted Tweets to be visible in mobile apps and will start appearing in users’ timelines on mobile apps.

“Initially, a small number of users may see Promoted Tweets near the top of their timelines from brands they already follow,” said the company. “This will help ensure that people see important Tweets from the brands they care about.”
