Major CDN provider serving as infrastructure layer for digital content and advertising delivery
Edgecast (now known as Edgio) is a content delivery network (CDN) and edge computing platform provider that serves enterprises, media companies, and digital platforms globally. The company provides infrastructure solutions for accelerating content delivery, streaming media, web application performance, and edge security services. While not a pure-play AdTech company, Edgecast plays a supporting role in the digital advertising ecosystem by providing the underlying infrastructure that enables fast, reliable delivery of ad content, video ads, and rich media experiences across websites and applications. Edgecast was acquired by Verizon Communications in 2013 and became part of Verizon Digital Media Services. In 2021, the CDN business was spun out and merged with Limelight Networks to form Edgio, which continued to operate the Edgecast platform. The company competes with major CDN providers like Akamai, Cloudflare, and Fastly in delivering low-latency content distribution services that are critical for digital advertising performance and user experience.
