History about 4x4 and SUV's

Early SUVs were descendants from commercial and military vehicles as the World War II Jeep and Land Rover. 

The first examples of longer-wheelbase wagon-type SUVs were the Chevrolet Carryall Suburban (1935, RWD only), GAZ-61 (1938, 4×4), Willys Jeep Station Wagon (1948), Pobeda M-72 (GAZ-M20/1955), which Russian references credit as possibly being the first modern SUV (with unitary body rather than body-on-frame), International Harvester Travelall (1953), Land Rover Series II 109 (1958), and the International Harvester Scout 80 (1961). These were followed by the more 'modern' Jeep Wagoneer (1963),International Harvester Scout II (1971), Ford Bronco (1966), Toyota Land Cruiser FJ-55 (1968), the Chevrolet Blazer / GMC Jimmy (1969), and the Land Rover Range Rover (1970). The actual term "sport utility vehicle" did not come into wide popular usage until the late 1980s; many of these vehicles were marketed during their era as station wagons.
