My hometown of Albany, New York is like Oklahoma City when it comes to finding old news footage. In other words, there are some clips from TV Stations but very little. Here's what I can't find yet:
WNYT: Anything pre-1985 (including their WAST days), 1988-1991 (when they used "We Know What Matters," the NMSA has an audio sample), and 1991-1994 (during the early days of "Newschannel 13").
WTEN: Pre-1984 (when they used "Hello News"), 1986-1988 (during the early days of the "Right at Home" era), and some late 1990s clips are missing (when they began using "Primetime News").
WRGB: Anything before 1981 (when they were an NBC Affiliate), 1989-1993 (the first era of "Making a Difference") and the later days of "NewsCenter 6" (mid 90s-98)
WXXA: When they launched their News operation in 1996 to 2000
