Los Angeles, California has always been a unique market. As the #2 market in the country, and a radio dial filled with signals from top to bottom, LA Radio has been a "starting point" for many hits and trends. With the proximity of the movie studios, LA Television has had access to more talent than most other markets combined. With such resources, creativity has been a hallmark of the market.

The history of broadcasting in Los Angeles is filled with interesting stories, from car dealers to religious figures.  We invite you to visit, enjoy, even share some history with us.
