About Us

Founded in 1964, Bonneville International's heritage traces its early roots to KSL Radio, which first went on the air in May of 1922 (originally as KZN) in Salt Lake City, and to KSL-TV, which had its on-air debut in 1949. Based in Salt Lake City, Bonneville International owns and operates 14 radio stations in Seattle, Phoenix, Denver and Salt Lake City as well as Salt Lake City’s premier television station, KSL-TV.

Bonneville International is among the premier broadcasting companies in the nation and takes great pride in its reputation as an innovative and dynamic company.  Its television and radio stations provide leadership that builds up, connects, informs and celebrates the communities in which they serve. Whether they are producing responsive public affairs programming, creating a local PSA campaign, engineering an on-site live broadcast in support of a charity, or utilizing the incomparable local news-gathering capabilities of its news and talk properties, they support their local communities.
