It was right around the time that the networks gave up on having a Saturday Morning and/or an after school cartoon line-up. All the new cartoons were coming from a syndicated programming block package and/or Cable Networks who were not subject to the same broadcast standards as the major networks. As it became easier for networks to fill their broadcast hours with infomercials and talk shows instead of cartoons, and since cable networks didn't have the same scope or audience as the majors, there just weren't any real valid targets left.
