One other correction: it was All-American that became Action Zone, in 1994. Action Zone was mostly Challenge with an added feature match, a format that lasted for about a year when it became basically All-American all over again, a strict recap show. That lasted for about another year (all of these switches started roughly with the new fall season) when Superstars switched from syndication to USA. Superstars itself became a recap show in January of '97.
At some point, I think in early-to-mid '86, Tuesday Night Titans moved to Friday nights and simply became TNT.
