The opening Control Voice came first during first three episodes ("The Galaxy Being", "The Hundred Days of the Dragon" and "The Architects of Fear"). Then, the executives wanted to see the "Bear" (their name for the monster in the story) first so, beginning with the 4th episode ("The Man With The Power") it would begin with a scene from the show where the Bear made an appearance. Then, the opening Control Voice would start the show, a commercial, then the Control Voice prelude as the show began. That continued throughout the entire first season to the 32nd episode ("The Forms of Things Unknown"). With the beginning of the second season, the 33rd episode ("Soldier") began with not only the Bear but also the Control Voice prelude, which continued to the 49th and final episode ("The Probe").
