However, close to half of PTEN's initial affiliates were stations that were already affiliated with Fox; as a result, these stations usually scheduled PTEN programming around Fox's then five-night prime time schedule (although Fox would expand its schedule to seven nights with the addition of programming on Tuesdays and Wednesdays on January 19, 1993, the day before PTEN launched). PTEN launched on January 20, 1993, with two series: the science fiction series "Time Trax" and the action drama "".
