Welsby began his broadcasting career on Liverpoolradio stationRadio City as a sports reporter and commentator. In January 1978 he joined Granada Television, working on its football programme The Kick Off Match and presented its 1980s successors Match Night and Match Time until their demise in 1983. Welsby was primarily a presenter, but did occasionally deputise as commentator. When Granada revived Kick Off in 1989 after a six-year absence, Welsby returned as presenter despite by then presenting networked shows. He was one of the anchors of the 1988 Seoul Olympics, the last Olympic Games to be covered by the network, and also presented the Saturday afternoon Results Service from 1985 onwards. Welsby occasionally presented live matches for ITV in 1986, becoming the regular host in 1987-88. At the start of the 1988-89 season, ITV began broadcasting exclusive live coverage of the Football League. It was the task of Greg Dyke to oversee the coverage and he entrusted Welsby as presenter of The Match, anchoring numerous dramatic matches over the next four years-most notably Arsenal's 2-0 win against Liverpool in the last game of the season which saw the Gunners snatch a last minute winner at Anfield. The loss of top flight football to Sky Sports in 1992 hit ITV Sport hard, and Welsby's final work as ITV's lead football presenter was at the 1992 European Championship. After this, he ceased working for ITV Sport and returned to Granada full-time. Welsby continued to present regional programming for Granada, including Granada Goals Extra, The Granada Match, the station's crown green bowls coverage, and the midweek sports programming until May 2000 when the station decided not to renew his contract. In an interview in 2015 Welsby was critical of Soccer Sunday, the last programme he presented, branding it a "poor show with poor content and poor journalistic standards". Welsby occasionally returned as a guest on the Granada Soccer Night programme, and in 2001 he went back to radio to present Elton Welsby's Soccer Saturday for North-West regional station Century FM - a role he held for three years.
