WGN No More?

[Kid]

I don't know anything about this stuff, so I am fully willing to be educated/proven wrong, but I believe the split in feeds happened something like 10-15 years before WGN dropped sports.  When WGN became a WB affiliate when the WB launched in like 1995, WB programming was shown on the superstation.  Years later (I'm thinking sometime in the late 90s or early 00s, but before WB and UPN merged to become the CW and WGN became a CW affiliate), they stopped showing WB programming on the superstation.  So unless there was something else to stop being the superstation, I don't know if the split in feeds does that.
