U.S. International Media was started in 2004 when Dennis Holt, who earlier had built Western International Media Corporation into the world’s largest and most diversified media management company, persuaded some of America’s most experienced and talented media professionals to join him in delivering on an idea so old fashioned that it almost seemed brand new: superlative service from a media planning and buying agency.

Over 80 percent of USIM's current employees are Western International Media Corporation alums, which provides significant knowledge continuity and competitive advantages. After only seven years of operation, U.S. International Media has grown to become one of the largest independent media agencies in the business, serving more than 200 clients from 21 U.S. and 9 international offices. Projected 2011 billings are $594 million.
