There are even more Phoenix news bones to pick:
http://www.youtube.com/watch?v=5N0FgrCIhmg (2:05): "News 5 is a part of the past, the present, and the future of Arizona" – 1988 news promo for the Downey/Turley/Cochran team. "Weekdays at 11:30 and every night at 9:30." Also: a riveting KTSP news promo (they once sent their correspondents throughout the world!?) and Diane Ryan newsbreak (she's still there!)
http://www.youtube.com/watch?v=SYKangZqJeU (8:15): KNXV News 15 at 10, January 1, 2002 (with odd news theme)
Cameron Harper evidently made a second layover in Phoenix between his KTVT and WPTY stints. The dating is easy: "Happy New Year", Bin Laden news stories, and (on the L3 at the end of the KNXV clip) not News 15, but ABC 15 News (which they adopted TV by Design gave them and WMAR a major refresh later in the year). The NMSA now is missing three different news themes for KNXV.
