Google Marketing Platform

Google Marketing Platform is an online advertising and analytics platform developed by Google and launched in July 24, 2018. It unifies DoubleClick's advertising services (acquired in March 2008) and Google's own advertising and analytics services. Google Marketing Platform is mainly used by big advertisers to buy ads on Internet.
Google Ads (launched in 2000) and Google Ad Manager (launched in 2010) are not parts of Google Marketing Platform. The three brands are complementary tools targeting different types of ad buyers and presenting slightly different features. However, the addition of Google Marketing Platform to Google's previous offers causes a lot of confusion for people looking to buy ads via Google.
