We get that, in a strange, supernatural world, things are always evolving. Take Superman. He's also known in certain quarters as Clark Kent (hope that wasn't too much of a spoiler), but, even before arriving at the Daily Planet, he was called Kal-El, Son of Jor-El back on Krypton. He's goes by The Man of Steel sometimes. Guy's got A LOT of nameage going on, even for a man with a secret identity.
In short, names change depending on the circumstances, but they seem to change more often when science fiction is the norm and men in horn-rimmed glasses can fly. And so hearing about the Sci Fi Channel getting rebranded as Syfy doesn't phase us one bit.
The New York Times astutely pointed out the continuing confusion over the years between SciFi the channel (which is owned by NBC/Universal) vs. Sci-Fi the genre (and all the other various permutations). Syfy is just Syfy, no dashes or spaces or anything. But don't say "See-fee," however -- it is still pronounced the way it has been since the cable channel debuted in the early 1990s.
A number of shows shot around town have been Sci Fi mainstays (hello, "Battlestar Galactica), but the channel was also instrumental in saving the Minnesota-based "Mystery Science Theatre 3000" back in the day, and for that we shall be eternally grateful.
And again, there's another property that saw its name evolve over time (to "MST3K"). Which just goes to show you -- it's not what you're called, but what you deliver, that ultimately matters.
