Warner Bros.' .... 75th Anniversary?

So, apparently in 1998, there was a Warner Bros.' 75th anniversary film festival, at which 33 films were shown. With 12 times as many slots to fill, it looks as if TCM is showing every one of the pre-1975 selections except for The Exorcist and Blazing Saddles. The only post-1975 selection that made the TCM lineup is Superman.
