In 1959 and 1960 it became very popular to have outdoor commercial "jump centres" or "trampoline parks" in many places in North America where people could enjoy recreational trampolining. However, these tended to have a high accident rate and the public's interest rapidly waned.In recent years, indoor commercial trampoline parks have made a come-back with a number of franchises set up across the United States and Canada. These are located indoors. They have wall to wall trampolines to prevent people falling off the trampolines on to hard surfaces. There are padded or spring walls to protect people from impact injuries. Despite these precautions there has been at least one death recorded due to a bad head first landing at a trampoline park.
