Lois reveals that her password, for the old Daily Planet computer system, is "Superman". However, barely a minute earlier, Lois states that the system was replaced three years ago. Two years before Superman first appeared in the pilot (1993).
During the first conversation between Dragonetti (John Shea) and Bill Robertson (Dean Cain), in Dragonetti's office, you can see a boom mic above Shea's head, after he lights his cigarette, while sitting at his desk. It is visible in 2 shots of him, in this scene.
