For some reason that probably only makes sense to marketroids, when they redesigned their website in 2000 they changed its URL from the logical wpbf.com to the awkward and silly-sounding TheWPBFChannel.com. They generally work in some sort of ad, promo, or other mention of this site address approximately every 2 minutes throughout their broadcast day.
