I may have asked this before, but don't recall: An oddity that I've noticed on Bangor television is that, for the past three years or so, WABI-5 (CBS) has been featuring actualities from WMTW-8, Portland's ABC affiliate, on its local newscasts. Meanwhile, WVII-7 (ABC) carries actualities from WGME-13 (CBS) in Portland. It used to be that the Bangor stations carried news reports from their Portland network counterparts. What happened to change this? ???
