What is the difference between O&O and Programmatic Digital Advertising?
In short, it is client owned inventory or other websites' inventory, and the difference is Control, scale and margins.
Owned & Operated (O&O) is station website inventory which is leveraged first (ideally) - then programmatic extends on OTHER websites outside of the Owned and operated sites.

O&O Digital Advertising (SoCast Engage): This is your premium, direct-sold inventory, you have complete control over the environment and typically keep higher advertising margins.
Examples include display banners on your homepage, video pre-roll ads before your radio stream, or sponsored blog posts.
LIMITED impressions: typically providing access to only thousands of impressions. Engage is specifically designed for broadcasters to easily manage content and create sophisticated advertising opportunities.
Programmatic Advertising (SoCast Reach): This is where you leverage automated systems and ad exchanges to place ads across a vast network of external websites, apps, and streaming services giving you access to trillions of impressions, allowing us to extend a client's reach beyond your radio station's inventory.
