when was astroturf invented?
The term is sometimes used as a generic description of any kind of artificial turf. AstroTurf was invented in 1965 by employees of Monsanto and patented in 1967 under the name Chemgrass.. It was renamed AstroTurf after its first well-publicised use at the Houston Astrodome baseball stadium. The advantage of AstroTurf over grass turf is quite evident: an artificial turf requires minimal maintenance.
