Artificial turf gained a bad reputation on both sides of the Atlantic with fans and especially with players. The first-generation artificial turf surfaces were carpet-like in their look and feel, and thusly, a far harder surface than grass and soon became known as an unforgiving playing surface that was prone to cause more injuries, and in particular, more serious joint injuries, than would comparatively be suffered on a grass surface. This turf was also regarded as aesthetically unappealing to many fans.
