From the 1950s until well into the 1970s, vending machines were used at American airports to sell life insurance policies covering death, in the event that the buyer’s flight crashed. However, this practice gradually disappeared due to the tendency of American courts to strictly construe such policies against their sellers, such as Mutual of Omaha. From 2000-2010, specialization of vending machines became more common.
Vending extended increasingly into non-traditional areas like electronics, or even artwork or short stories. Machines of this new category are generally called Automated Retail kiosks. The trend of specialization and proliferation of vending machines is perhaps most apparent in Japan where vending machines sell products from toilet paper to hot meals and pornography, and there is 1 vending machine per 23 people.
