WNMB (900 AM) is a radio station licensed to North Myrtle Beach, South Carolina, USA, and serves the greater Myrtle Beach area. The Colonial Media and Entertainment outlet is licensed by the Federal Communications Commission (FCC) to broadcast at 900 kHz with a power of 500 watts. WNMB is currently silent, undergoing repairs. The station goes by the name "AM Stereo 900" and its current slogan is "The Sound of North Myrtle Beach." They most recently broadcast in high fidelity C-QUAM AM Stereo under a beach-oriented oldies format. Until August 1, 2015, WNMB was owned and operated by the family of Bill and Suzy Norman who were original employees of the original WNMB when it signed on in 1972. WNMB FM existed from 1972-2000 when it was sold and the call letters changed to WEZV. Soon after, Bill Norman leased the AM station and changed the call letters to WNMB. Norman later purchased WNMB outright and continued the WNMB radio tradition on the Grand Strand.
In 2000, Fidelity Broadcasting moved the WNMB letters to WGSN when the FM became WEZV. At first, WNMB aired the same easy listening music as WEZV. Starting in 2001, WNMB was leased by Bill Norman, who managed WNMB FM in the 1970s and returned to the area after 20 years in Albemarle, North Carolina. Norman also became the morning host, while his wife Susi Norman, also a WNMB FM employee in the early days, took the midday shift. Larry Schropp, another member of the WNMB FM team, was the afternoon DJ.
On January 19, 2011, Ted Bell's "All Request Beach Cafe" lunch hour show moved to WNMB from WVCO. In late April 2011, WNMB owner Bill Norman resurrected WVCO. Ted Bell moved mainly back over to The Surf (where he had been previously for about 11 years). However, Bell can still be heard on WNMB as well. Both radio stations are now located together in the WNMB building on Pine Avenue in North Myrtle Beach.
In 2014, WNMB changed from playing 1950s' and '60s' music to playing music from the '60s, '70s, and '80s. Previously,under Mr. Norman's tenure, the station had played a wide range of true golden oldies and had a considerable audience. Also, Mr. Norman was active in the community and had many advertising clients on his air. After the shift in music, the station's identity changed dramatically. The station did continue serving the community. The North Myrtle Beach High School "Coaches Show" aired Wednesdays and Thursdays during the evening. Many of WNMB's former listeners greatly miss Mr. Norman and the wonderful oldies format.
On May 15, 2015, it was reported that an agreement had been reached to sell WNMB to Beatty Broadcasting Company for $25,000 with an option to buy the tower site for $150,000. The sale was consummated on August 1, 2015. WNMB was reported in the North Myrtle Beach Times as silent on November 12, 2015, with general manager Gary Beatty citing factors such as "FCC restrictions on the station's signal and the status of AM radio in general" as well as the death of former owner Bill Norman contributing to the decision. The station is listed as "licensed and silent" as of November 12, 2015 in the FCC's CDBS station search. 
Effective June 21, 2016, Beatty Broadcasting sold WNMB's license to Colonial Radio Group, Inc. (Olean, New York-based Colonial Media and Entertainment) for $1,000. Colonial aims to relaunch the station in fall 2016.
Death of WNMB owner Bill Norman and subsequent investigation
Owner Bill Norman suffered a serious stroke on September 29, 2012, and died at Grand Strand Regional Medical Center on October 14, 2012, from what initially was labelled a "cerebral vascular accident" on the death certificate. On October 19, 2012, the Myrtle Beach Police Department launched an investigation into Norman's death. WMBF-TV reported on December 6–7, 2012, that a 53-year-old nurse, Janet Kupka, had given Norman 20 milligrams of morphine instead of the prescribed 4 milligrams. Kupka allegedly admitted to a witness that she gave Norman the drug Diprivan. Norman was brain dead due to the stroke. Norman's body had been cremated and was not available to be autopsied. The cause of death may be changed to an overdose. In a filing with the FCC, Norman's widow is listed as his personal representative and owns 50% of WNMB in that capacity, in addition to the 50% stake she already held.
