This document discusses designing a GraphQL API for a Netflix service across browsers, mobile apps, and TV. It describes a Movie type with different fields returned depending on the device. A new requirement is added that some mobile devices cannot accept posters, requiring an optional poster field. GraphQL was created by Facebook in 2012 and released in 2015. It is a query language for APIs that allows flexible data fetching.
