The latest Nielsen Audio PPM ratings for May 2026 reveal a dynamic landscape in the radio industry, with several stations making significant strides and others facing challenges. In Washington DC, Public News/Talk 88.5 WAMU has risen to the top spot, while Hubbard News 103.5 WTOP has seen a decline. The ongoing lawsuit between Cumulus Media and Nielsen has impacted the ratings, with Cumulus Media's stations no longer publicly listed. Boston's WBUR remains a strong contender, but Beasley's WROR has made impressive gains. Miami/Fort Lauderdale's WMIA-FM has soared to the top, while Cox's WFEZ and WAMR have seen fluctuations. Seattle/Tacoma's KUOW-FM maintains its lead, while Bonneville's KIRO has climbed. Phoenix's KSLX has reclaimed the top spot, and Detroit's WXYT-FM has faced a decline. Minneapolis/St. Paul's KQQL and KEEY have tied for first, while Audacy's KMNB has made gains. Tampa/St. Petersburg's WCIE has seen an increase, and Denver's KOSI has returned to the top spot. San Diego's KXSN has risen, while Baltimore's WWIN-FM has grown its lead. St. Louis's KSHE 95 has taken the market lead, and Gateway Creative's KLJY has seen an increase. These ratings provide valuable insights into the radio industry's health and the strategies of various stations, but they also highlight the impact of external factors such as lawsuits and the evolving preferences of listeners.
