You are spot on, except I will add that that back in the day there was a lot of bourbon consumed with a long pull off the bottle followed by a "chaser" of choice (usually Coke or 7-UP) by people that weren't "plantation" level!...vodka became the spirit of choice in the 60's-70's because it was inexpensive, it was mixable with practically anything, and folks had the idea it wasn't detectable on the breath...distillers loved it because it was cheap to make and it was in the still today and on the store shelf tomorrow...the only problem with vodka was that most suppliers had at least one, some two or three in their portfolios, and the profit margins at retail were very thin due to heavy competition until the arrival of "super premium" Absolut from Sweden and Stoli from Latvia, which significantly upped the profits for everyone...it is ironic that today the #1 selling spirit brand is Titos, a mid-priced vodka made in Austin, Texas with a home-made look started by a guy selling it out of the trunk of his car in rural Texas...as good a brand for us as Absolut was, Titos is a phenomenon that I doubt will ever be repeated again, a fascinating story in itself...even as bourbon was on the decline in the mid-60's, many credit the arrival of Blantons Single Barrel in 1964 as keeping bourbon somewhat relevant...it was a "new" expression in a tired category and along with PVW becoming what it is these set the stage for the resurgence of bourbon in the mi-2000's...and as you stated very prominent in the exposure of bourbon to a new category of drinkers was the TV shows you mentioned plus It's A Mad Mad World...the spirits business is truly a what goes around come around business, the trick is to figure out when it's coming vs going!
