Artificial turf first gained substantial attention in 1966, when it was installed in the year-old Astrodome. The specific product used was "ChemGrass", developed by Monsanto and rebranded as AstroTurf; this term since then became a generic trademark for any artificial turf throughout the late 20th century. AstroTurf remains a registered trademark but is no longer owned by Monsanto.
