The Six Million Dollar Man
In 1975, a two-part episode entitled "The Bionic Woman", written for television by Kenneth Johnson, introduced the lead character Jaime Sommers (played by Lindsay Wagner), a professional tennis player who rekindled an old romance with Austin, only to experience a parachuting accident that resulted in her being given bionic parts similar to Austin. Ultimately, her body "rejected" her bionic hardware and she died. The character was very popular, however, and the following season it was revealed that she had actually survived, having been saved by an experimental cryogenic procedure, and she was given her own spin-off series, "The Bionic Woman". This spin-off ran until 1978 when both it and "The Six Million Dollar Man" were simultaneously cancelled, though the two series were on different networks when their final seasons aired.
Wonder Woman (1974 film)
Wonder Woman is a 1974 American made-for-television superhero film based on the DC Comics character of the same name, directed by Vincent McEveety and starring Cathy Lee Crosby. The film was a pilot for an intended television series being considered by ABC. Ratings were described as "respectable but not exactly wondrous," and ABC did not pick up the pilot. 
Instead, Warner Brothers and ABC developed a different Wonder Woman television concept that fit the more traditional presentation of the character as created by William Moulton Marston, turning away from the 1968–72 era that had influenced the pilot. "", which premiered in 1975, starred Lynda Carter and eventually led to the "Wonder Woman" TV series. Crosby would later claim that she was offered the chance to reprise the role in that series.
