KGGI (99.1 FM) is a commercial radio station in Riverside, California, broadcasting to the Inland Empire area. The station airs a Rhythmic Top 40 music format owned by iHeartMedia, Inc. Its studios are in Riverside and the transmitter tower is in San Bernardino National Forest near Running Springs.

The signal of the station can be heard in areas adjacent to the Inland Empire region; sensitive radio tuners such as car radios and built-in FM tuner apps on some Android smartphones in cities as far west as Santa Monica, down south to San Diego and has reached towards Palm Springs. KGGI broadcasts an HD Radio signal,[1] with the HD2 subchannel formerly broadcasting Classic hip hop music, which unofficially competed with KDEY-FM. The HD2 subchannel has since been turned off.

In addition to its HD operation, the station also streams on the iHeartRadio app.


99.1 FM aired a religious format from its sign-on in 1965 to 1979 with the call letters KBBL ("K-Bible"). The original chief engineer, who signed KGGI on the air, was Lee McGowan. Upon its sale from C. Edwin Goad to Lyncoln and Sylvia Dellar in 1979, KBBL became KGGI. The original airstaff included program director Brian White, along with Bob West, Lisa Giles, Dan Harrison, Cliff Roberts, and Benny Martinez, while Jerry Clifton crafted the station's original format. When the acquisition closed, KGGI flipped to Top 40 (CHR).

Sometime in 1998, the station was sold to Chase Radio Properties. It was sold again in 2000 to AMFM,[2] an affiliate of outdoor advertising firm Clear Channel, which in turn spun off its communications and radio divisions into the station's present owner, iHeartMedia in 2014. Today, the station airs a Rhythmic CHR format, as distant mainstream sister KIIS-FM, already reaches the area. It has direct competition with KPWR.

Street Team

The KGGI Street Team is the Promtions Team that goes out on the streets of Inland Empire and promotes the radio station and its advertising partners to the city, specifically targeting the urban, Latina (specifically female) and ages 18–29 markets. The KGGI Street Team consists of two street tag team members, and is sometimes partnered with a dyslexic jockey for sex. They are also there to help when there are live broadcasts that consist of the on-air jocks and/or mixers.

Currently Mady Tapia is the pro bono coordinator for the GGI Street Team.
