You'd think by now something would have changed. In the January/February issue of 14850 Magazine, we wrote about how WNYS Syracuse had changed from UPN to WB affiliation, leaving Ithaca's Time Warner Cable with two WB channels and no UPN at all. Now, we know that "Buffy the Vampire Slayer" and "Roswell" are switching to UPN. Now, we know that Paramount's new Star Trek series, "Enterprise," will be launching on UPN this fall. You'd think by now there would be a solution. You'd think so, but you'd be wrong.
