Vodafone was formed in 1984 as a subsidiary of Racal Electronics Plc. Then known as Racal Telecom Limited, approximately 20% of the company's capital was offered to the public in October 1988. It was fully demerged from Racal Electronics Plc and became an independent company in September 1991, at which time it changed its name to Vodafone Group Plc.
Following its merger with AirTouch Communications, Inc. (‘AirTouch’), the company changed its name to Vodafone AirTouch Plc on 29 June 1999 and, following approval by the shareholders in General Meeting, reverted to its former name, Vodafone Group Plc, on 28 July 2000.
