48 Hours is an
American documentary/
news magazine television series broadcast on
CBS. The series has been broadcast on the network since January 19, 1988. The program airs Saturdays at 10:00 p.m.
Eastern and
Pacific Time, as part of the network's placeholder
Crimetime Saturday block; as such, it is currently one of only two remaining first-run
prime time programs (excluding
sports) airing Saturday nights on the major U.S. broadcast television networks (along with
Univision's
Sabadazo). The program sometimes airs two-hour editions or two consecutive one-hour editions, depending on the subject involved or to serve as
counterprogramming against other networks.
