Founded by Dennis Holt in 2004, USIM is the most diversified, fastest growing, full-service media management company in the United States. We currently have employees located in 20 offices across the U.S. and Canada. This strategically organized network enables us to provide ongoing support to both advertising agencies and in-house agencies/clients, which is beneficial for national and local media management. USIM is one of the few local-market-focused agencies with the expertise and experience to access the fragmented - but critical - local marketplace.

USIM was awarded MEDIA Magazine’s Independent Media Buying Service of the Year for 2009.

In December 2010, USIM acquired enCircle Media, Inc., a worldwide-recognized leading digital advertising agency. In December 2011, the company changed its name to U.S. Interactive Media to better align with its parent agency, USIM.

Dennis Holt was also the Founder and Chairman of Western International Media Corporation, which grew into an $11 billion media management company, until it was sold to The Interpublic Group of Companies in 1995, and subsequently renamed Initiative Media.
