PTEN had three strikes against it going in, which all but scuttled the intent to turn it into a real network:
- The participating stations generally got to choose when on their schedule the PTEN programs would air. Presumably, an interest in getting a return on their investment would lead to scheduling the programs in Prime Time broadcast slots, but this was not always the case (in large part because close to half of its stations were already Fox affiliates), as fans of the nascent network's offerings would soon find out.
- A completely different division of Warner Bros. TV was already in the process of setting up the network which would become The WB.
- Chris-Craft, a boat maker which happened to get into television (by way of United Television/BHC Communications), decided to hitch its wagon to Paramount Pictures and, with their stations and those of Paramount note as the nucleus, launched UPN, which ate up PTEN's prime time slots and pushed their shows into the Friday Night Death Slot, late night or Saturday afternoons, which were among the busiest timeslots for syndicated programming in The '90s.
The internal conflict within Warner Bros. and Chris-Craft's apathy guaranteed that one of their projects would be killed, and PTEN was the loser.
PTEN lasted only four years (1993-1997), and in its final seasons was kept alive solely by its one surviving program: Babylon 5.
