Radio
In February 1995, Elliott was given a new nickname as "Mike the Mouth" when he launched the first late night talk show on 100-102 Century FM in the North East. He was suspended in his first year at the station for swearing at a woman caller who said she was a benefits swindler, but was reinstated after fans protested outside of the station's studios in Gateshead. In January 2000, he was taken off the air in the middle of his show, following an expletive-filled outburst at a caller. Bosses sacked him, assuming, from his behavior and slurred speech, that he was drunk. However, Elliott claimed that his "strange behavior" was caused by combining two glasses of wine during a family meal with the cold remedies Benylin and Night Nurse. In June that year, he was reinstated by the station. In 2001, he launched a board game called Social Insecurity, with some similarities to Monopoly. In December 2002, a new Mike Elliott radio show launched on North East Magic Radio in the same slot as his previous program. However, on MW, it failed to gain the same number of listeners that the Century FM series had achieved and Elliott was released from his contract in July 2003. In December 2003, Elliott went back on air on Sunderland's Sun FM. In January 2006, the series was re-branded North South Divided, pitching the northern stations of the Local Radio Company against their southern counterparts. Broadcast over almost 30 stations, this was the first time listeners outside of the North East had a taste of Elliott, alongside another presenter, Alex Dyke. On 5 July 2006, North South Divided ended.
Death
On 23 December 2014, Elliott died of esophageal cancer at age 68.
