I can appreciate this comparison, and it ties into what @Samantha was saying earlier about Scripps' values in journalism. The KSHB rebrand did a great job at utilizing the channel number as the brand and slogan- I end up in KC a decent amount and remember seeing the "News For Every One" (Stories, A Voice, A Community...). I remember thinking the approach was unique and built a community-minded angle that seemed to take a stab at first-place KMBC/Hearst, where many stories in the newscast are introed "covering (location) tonight". The positioning for KSHB also is a good setting/base for ScrippsCast (can argue that later).
Has it pulled KSHB out of 4h place? Not sure. Would love to know if there was a dent made. If northing else, there is likely a greater brand awareness for Channel 41. However, to the point, there are now 4 newscasts in Detroit. if WXYZ is not in 1st place and ratings are lagging or sinking, this might be worth a shot. Including Detroit as the brand might also be a stab at CBS (Again, has WWJ made any dent in the ratings or is there any trend showing they are on track to?)
