Elon Musk's X, formerly Twitter, is introducing new ad targeting features to compete with YouTube, owned by Alphabet Inc. (GOOG, GOOGL). The features allow advertisers to run ads before videos of chosen creators, on the main timeline, and creators' profiles. This initiative aims to attract video creators and advertisers by offering a revenue-sharing model, though the percentage of ad revenue shared with creators is undisclosed. The move follows Musk's efforts to improve content quality on X by partnering with notable figures and aims to regain advertisers' trust after a decline in ad revenue.
