TJW was on a slow decline anyway. The writing was on the wall even before Barry's death.
Some numbers from May 1984 in Variety shows it was only being seen in 62 markets, compared to 110 for Wheel, 139 for Feud and even 90 for TTD. As far as ratings, TJW was pulling in a 4.8 compared to Wheel's massive 12.3, Feud's 9.6 and TTD's 5.7.
I found the thread in question that included what I found in the World Almanacs. By the
November 1984 sweeps, both
Joker and
Tic Tac fell out of the Top 20. Interestingly enough,
Feud remained a Top 5 show.
Also in that thread, you linked to another
Variety article from April 1985. By that point,
TJW plummeted to the bottom of the pack, and lost nearly another two dozen markets. I'm genuinely surprised that and
TTD (62 markets at that point) made it to the next season.
