SAN FRANCISCO (KRON) — KGO 810, a long-running radio station that Bay Area listeners have been tuning in to for the last 80 years abruptly announced that it was going off the air on Thursday. The station, which specialized in news and talk radio, didn’t offer much in the way of an explanation as to why it would cease to broadcast.

In a post on its website, the station thanked listeners “for your loyalty and for trusting KGO to be our source for information.” The post continued, “We also want to sincerely thank all the talented men and women that worked so hard over the years to produce award-winning programming on KGO.”

While little was offered as to why, the post did indicate that something new would be coming to that spot on the terrestrial radio dial.

“On Monday, 810am begins a new era,” the post read. “We hope you will tune in.”

KRON4 tuned in to 810 on the dial and heard promos with the sounds of slot machines interspersed with songs suggestive of gambling like Lady Gaga’s “Poker Face,” ABBA’s “The Winner Takes it All,” and the Pet Shop Boys’ “Opportunities.”

Mark Thompson, a longtime host at the station tweeted a “Thanks to everyone who was reached out on this day,” and confirming that “the KGO we knew as a talk station is going away.”

“The broadcast industry and all ad-supported legacy media are in brutal times. Sadly, that brutality hit us suddenly and completely,” the tweet went on to say.
