# Interpublic Group (IPG)

> Interpublic Group built the modern advertising holding-company model: autonomous creative, media, PR, healthcare and data agencies gathered under one corporate roof. Its network included McCann, FCB, IPG Mediabrands, Weber Shandwick, Acxiom and KINESSO. After a $2.3 billion push into customer data, weakening media performance and major account losses exposed the limits of being the smaller global network. Omnicom completed its all-stock acquisition of IPG in November 2025, ending IPG's run as an independent public company and folding its people, clients and identity assets into a larger marketing platform.
