Emerging digital advertising platforms like native ads, immersive ads, and web-in-page ads are allowing publishers to generate new revenue streams. Native ads in particular are tipped to become one of the most widely used formats as publishers work more closely with advertisers. Publishers are also developing new types of native content like video playlists, social media streams, and mobile flipbooks to engage audiences. However, there are also concerns about a lack of standards and definitions around native advertising.
