WBZ stopped referring to itself as "4" anything several years ago. I'd always figured if they ever went back to channel numbers they'd use WBZ 30 to tie in with WBZ 1030.
Oy...not this again

WBZ-TV is not "channel 30." Yes, it transmits to over-the-air viewers on 566-572 MHz, the bandwidth that was analog channel 30...but it is known to nobody (except a handful of pedantic folks on these boards) as "channel 30." I would guess that somewhere in the neighborhood of 90-95% of WBZ's viewers still punch in "4" or some variation thereof ("4.1" for OTA DT, 804 for HD on Comcast, etc.), while nobody - and I mean
nobody - punches in "30" to see WBZ. Why use that as a brand?
