For programmatic video, mobile accounts for two-thirds of spending. Mobile’s share of programmatic video spending is smaller than its share of total programmatic spending because connected TV (CTV) has become a popular device for video advertising.
In nonvideo programmatic advertising, there isn’t another device that eats away as much share as CTV does. Digital video is a large category that includes ads on streaming services, news sites, social networks, and more. Although CTV is the hottest subset of digital video, mobile is where most of the money’s at.
