The 1980s also saw the major English clubs, led by the likes of Martin Edwards of Manchester United, Irving Scholar of Tottenham Hotspur and David Dein of Arsenal, beginning to be transformed into business ventures that applied commercial principles to the running of the clubs, which led to the increasing power of the elite clubs. By threatening to break away, the top clubs from Division One managed to increase their voting power, and took 50% share of all television and sponsorship income in 1986. Revenue from television also became more important: the Football League received £6. 3 million for a two-year agreement in 1986, but by 1988, in a deal agreed with ITV, the price rose to £44 million over four years with the leading clubs taking 75% of the cash. The 1988 negotiations were conducted under the threat of ten clubs leaving to form a "super league", but were eventually persuaded to stay with the top clubs taking the lion share of the deal. As stadiums improved and match attendance and revenues rose, the country's top teams again considered leaving the Football League in order to capitalise on the influx of money into the sport.
