Update: Why WWE Superstars Was Cancelled

Partial Source: Pwinsider

WGN reportedly canceled WWE Superstars because the network was paying too much for what they were getting. The network was hoping that the show would help their national ratings, as they don't have a huge amount of coverage across the country, and because WWE is a proven ratings draw, the network thought that they might help them get picked up by other cable systems.

Unfortunately, due to the show's third-tier status, it did not get the ratings the company was looking for. Some talent in the company are concerned for their status with the loss of the show.
