By the late 1970's, EMI served the community through Christian bookstores in Neenah and Appleton, a graphics and printing company and WEMI-FM. During the late 1980's, the various locations of Evangel Christian Book Center were consolidated in a central location to create Wisconsin's largest Christian Bookstore. Ranking among the top 100 Christian bookstores nationwide, ECBC provided books, music, gifts and other materials for church ministry and personal Christian growth.

In 1989, WEMI moved into larger, more efficient facilities. Seeking to fulfill it's mission statement, EMI acquired WGNV-FM (88.5) in Central Wisconsin in 1991.

91.5, broadcasting to the Green Bay, Wisconsin and North area, was added to the EMI station stable in 1998. Called WEMY, it serves the Green Bay - Northern Wisconsin - Lake Shore listeners.

Radio is today the preferred medium to reach a well-defined audience. Unlike television viewers, radio listeners identify closely with their favorite station. Radio fits well into today's mobile lifestyle, and becomes a personal companion at home, at work, in the car - even out jogging. It is this intimate characteristic that makes radio so appropriate for Christian ministry, speaking to the heart of one person at a time - a hundred thousand times over.

The ministry of EMI builds on these inherent strengths to reach the people of Eastern and Central Wisconsin with the Christian message of hope and reconciliation.
