As part of a major format shuffling involving four of iHeart Seattle radio stations, on January 19, 2016, at 12:00 noon, after playing "Whatever You Like" by T.I., KUBE's long-time Rhythmic CHR format and branding moved to lower-power sister frequency KKBW, displacing their Active Rock format (which would tweak to Alternative and move to KYNW). At the same time, 93.3 adopted KBKS's Mainstream CHR format, added in some newer rhythmic titles to the playlist, and rebranded as "Power 93.3." New KPWK call letters took effect on January 26, 2016, the KUBE call letters moved to KKBW the same day.
