From the 1940s to the 1960s, broadcast television stations typically provided local news programs only one to two times each evening for 15 minutes (the normal length for many locally produced programs at the time); usually these programs aired as supplements to network-supplied evening news programs or leadouts for primetime programming. Reports featured on local and national television newscasts during this time were generally provided via film or still photography; eventually, videotape began to be used to provide live coverage of news events. The 1950s also saw the first use of airborne newsgathering; most notably, in 1958, Los Angeles television station KTLA began operating the "Telecopter", a helicopter equipped for newsgathering use that was the most advanced airborne television broadcast device of its time.
