(1950–1960), the Indy 500 awarded points towards the World Championship of Drivers. However, very few European entries even made an attempt to race at Indy. Noteworthy moments include the emotional victory by Sam Hanks in 1957, as well as the tragic death of two-time winner Bill Vukovich. The famous 1960 duel between Rodger Ward and Jim Rathmann set the race record for the most lead changes in Indy 500 history, a record that remarkably would not be broken until 2012. Indy legend A. J. Foyt debuted in 1958, and won his first 500 in 1961. In the fall of 1961, the last of the remaining original brick pavement was paved over in asphalt, and in 1962 Parnelli Jones famously broke the 150 mph barrier. Rear-engine revolution The 1960s. Sometimes referred to as the "British Invasion" or the "Decade of Innovation," it partly overlaps the aforementioned Roadster Era. In 1961, Jack Brabham arrived at Indy with a European, Grand Prix style, rear-engined machine. Against a field of venerable front-engined Offenhauser-powered roadsters, Brabham's car was considered diminutive and underpowered, however, it experienced exceptional handling in the relatively flat corners. The mechanical advantages of rear-engined cars were quickly realized, and rapidly began to displace their front-engined counterparts in the starting field. A. J. Foyt's win in 1964 was the last time a front-engine machine won the Indianapolis 500. In 1965, ABC Sports carried the race for the first time on Wide World of Sports, ushering in a new era of television coverage at Indy. Jim Clark won the race in a rear-engine machine, the first of its type to do so. By the end of the decade, the movement toward rear engine cars had over taken the sport. In 1969 not a single front-engined car would qualify. After a fiery fatal crash in 1964, USAC crafted rules to discourage, and eventually ban, the use of gasoline as a fuel. Decade of Legends The 1970s. After bolt-on wings started being allowed in 1972, speeds quickly climbed. Drivers went from laps in the 160 mph range a few years earlier, to flirting with the elusive and daunting 200 mph barrier. Turbocharged engines were the powerplants of choice, downforce levels increased substantially, and wide slick tires were now being used. It was both an entertaining spectacle for the fans, as well as a disaster waiting to happen, as safety features were not prepared for the rapid
