Ad networks often support a wide spectrum of ad formats (e.g. banners, native ads) and platforms (e.g. display, mobile, video). This is true for most ad networks. However, there also are ad networks that focus on particular kinds of inventory and ads:

Mobile ad networks, focus on the traffic generated via mobile web and mobile apps, and work with the corresponding ad formats.

Video ad networks serve ads via inventory, associated with online video content.

Video and mobile ad networks can be acquired by larger advertising companies, or operate as standalone entities.
