Content networks are usually 3rd party partners of an ad network where content or advertisements get syndicated. Sometimes there is full transparency allowing the buyer to see who these partners are and to choose which are allowed to run the advertising campaign, and sometimes no visibility is given into where the ads are displayed. Always ask your account managers for information about where your ads are displaying so you can determine if it is a good fit and learn what to avoid and what works best for you.
