DdB

DDB is an acronym with several distinct meanings across different fields. The exact meaning depends on the context in which it appears, and two of the more widely recognized uses are in advertising, digital libraries, and computer graphics.

DDB Worldwide Communications Group is a major international advertising network. It originated in 1949 as Doyle Dane Bernbach and grew into a globally operating agency group. Now part of the Omnicom Group, DDB Worldwide encompasses numerous agencies and campaigns around the world, known for a range of brand-building and creative advertising services.

Deutsche Digitale Bibliothek, abbreviated DDB, is a German federal initiative aimed at providing a single access point to digitized cultural heritage from German libraries, archives, and museums. Launched in the 2010s, it aggregates metadata and content from numerous institutions to facilitate nationwide and international discovery of Germany’s digital cultural holdings. The project collaborates with broader European digital libraries ecosystems to improve cross-border access.

In computing, DDB can stand for Device-Dependent Bitmap, a term used in some graphics systems (notably in AmigaOS and related environments) to describe a bitmap whose pixel data is stored in a format tied to a specific display device. This contrasts with device-independent representations, which aim to be portable across devices.

Because DDB is an acronym used by multiple organizations and technical terms, its precise meaning should be inferred from the surrounding context.
