WSM (AM)

WSM (650 kHz) is a commercial AM radio station, located in Nashville, Tennessee. It broadcasts a country music format (with classic country and Americana leanings, the latter of which is branded as "Route 650") and is known as the home of the Grand Ole Opry, the world's longest running radio program. The station is owned by Ryman Hospitality Properties, Inc. After nearly 40 years broadcasting from a studio within the Gaylord Opryland Resort & Convention Center, WSM moved to a showcase studio inside the former home of Roy Acuff, just outside the Grand Ole Opry House, in July 2024.

Nicknamed "The Air Castle of the South", the station broadcasts with 50,000 watts around the clock from a facility in Brentwood, Tennessee. It has one of the largest daytime coverage areas in the country, providing at least grade B coverage as far southeast as Chattanooga, as far northwest as Evansville, Indiana, as far west as Jackson, Tennessee and as far south as Huntsville, Alabama. At night, WSM's clear channel signal reaches much of North America and nearby countries.

WSM reaches a worldwide audience via its Internet simulcast. It is the National Primary Entry Point (PEP) for the Emergency Alert System (EAS) in Middle Tennessee and the southwestern portion of Indiana.

Bill Cody has been the host of the station's morning show, Coffee, Country and Cody since 1998, and has been in radio since 1975. Since its establishment on January 1, 2020, the country music oriented TV network Circle simulcast Coffee, Country, and Cody, following a period of several years where the Heartland network. Cody's Pure American Country syndicated show is flagshipped at WSM. Larry Gatlin, lead singer of the Gatlin Brothers, hosts an hourlong gospel program on the weekends as of 2016. Tracy Lawrence's syndicated program Honky Tonkin' has been flagshipped at WSM since 2015. Dailey & Vincent host a monthly radio show on the station.

Jason Coleman hosts a Sunday night piano music show in honor of his grandfather, longtime Nashville keyboardist Floyd Cramer.

The Grand Ole Opry fills several nights of the station's evening schedule. Following the Opry on most Saturday nights is the Midnite Jamboree, an aftershow that was originally founded by Ernest Tubb in 1947 and continues to be sponsored by Tubb's eponymous record shop. Following the Jamboree is the regionally syndicated Sutton Ole Time Music Hour.

In 2017, WSM launched "Route 650", a full-time Americana music streaming station available via its website, mobile app and services like TuneIn.

In 2018, WSM launched "Opry Nashville Radio", a full-time streaming station billed as being "based on the Grand Ole Opry and Nashville lifestyle" and focusing mainly on contemporary country music. During December, this channel flips to all Christmas music.
