Crown Broadcast is a division of International Radio & Electronics Corporation located in Elkhart, Indiana.  Crown began as International Radio and Electronics Corporation in 1947.  The founder's intent was to provide high-quality audio equipment to the broadcasting industry.

In the following decades, the company evolved into a world-class supplier of professional audio equipment and, later, of industrial power supplies and medical imaging power systems.  The name of the company was changed to Crown International in 1975.

Throughout 1997, Crown celebrated its 50th anniversary with special employee and community events.

In 2000, Crown International was purchased by Harman International, primarily for Crown's Pro Audio division.  As the Crown Broadcast division was not central to the vision of Harman International, remaining members of Crown's founding family secured the Broadcast division as a separate entity and brought it under the newly resurrected corporate name of International Radio and Electronics Corporation (IREC).

Today, Harman International (with Crown Pro Audio) and IREC (with Crown Broadcast) exist as separate corporate entities with shared roots.  More importantly, Crown Broadcast continues to fulfill the mission of the original International Radio and Electronics Corporation.
