“Amateur radio operators exchange QSL cards to confirm two-way radio contact between stations or a one-way reception of a signal from an AM radio, FM radio, television or shortwave broadcasting station. Each card contains details about one or more contacts, the station and its operator. A typical QSL card is the same size and made from the same material as a typical postcard, and most are sent through the mail. During the early days of radio broadcasting, the ability for a radio set to receive distant signals was a source of pride for many consumers and hobbyists. Listeners would mail \"reception reports\" to radio broadcasting stations in hopes of getting a written letter to officially verify they had heard a distant station. As the volume of reception reports increased, stations took to sending QSL cards containing a brief form that acknowledged reception. Collecting these cards became popular with radio listeners in the 1920s and 1930s, and reception reports were often used by early broadcasters to gauge the effectiveness of their transmissions” [adapted from Wikipedia].
