Top OTT and CTV Advertising Platforms: A Reference Guide
Consumer attention has steadily shifted away from traditional broadcast TV toward streaming services, and that migration has created significant new territory for AdTech. Connected TV (CTV) and over-the-top (OTT) advertising now represent two of the fastest-growing segments in digital media, attracting investment from both established players and newer entrants across the programmatic ecosystem.
The directory below covers the main connected TV devices, OTT video-streaming services, AdTech companies active in CTV/OTT, and video players and hosting platforms. Social media platforms that support video streaming (Facebook, Twitch, TikTok, Snapchat) are excluded from the streaming services section.
