About

Google Ad Manager is Alphabet's unified ad serving and monetization platform for digital publishers — combining what were previously two separate Google products (DoubleClick for Publishers/DFP for large publishers and Google Ad Exchange/AdX for programmatic demand) into a single platform that powers advertising for some of the world's largest media companies, broadcasters, and app developers. Part of Alphabet (NASDAQ: GOOGL), Google Ad Manager serves as the infrastructure layer through which publishers sell their advertising inventory across programmatic and direct channels.
