Mission: Impossible is an American television series, created and initially produced by Bruce Geller, chronicling the exploits of a team of secret government agents known as the Impossible Missions Force (IMF). In the first season the team is led by Dan Briggs, played by Steven Hill; Jim Phelps, played by Peter Graves, takes charge for the remaining seasons. Each episode opens with a fast-paced montage that unfolds as the series' theme music composed by Lalo Schifrin plays, after which in drama's prologue we see Briggs or Phelps receive his instructions from a voice delivered on a recording which then self-destructs.
The series was filmed and financed by Desilu Productions, and aired on the CBS network from September 1966 to March 1973. It was revived in 1988 for two seasons on ABC, retaining only Graves in the cast. It also inspired a series of theatrical motion pictures starring Tom Cruise, beginning in 1996. Wikipedia
