Stumbled across this site, which offers videos from 1960's-70's of local TV interviews (and some other coverage) for the 49ers and Raiders--as well as other Bay Area sports teams. Nothing really groundbreaking, but it's interesting to take a look at:

There's a similar trove of Dallas Cowboys features from the 1970s (and some from the 1960s), including Staubach talking about the fight with Longley, Hollywood Henderson interviewed right after being drafted, Too Tall Jones interviewed after being drafted, the Cowboys getting ready for the 1975 NFC Championship with the Rams, Walt Garrison whittling, and a ton of other stuff:
