Hellstorm's Files (season 9)

The fourth season of the animated comedy series Hellstorm's Files aired on Network/Warner from January 2, to August 18, 1989, and consisted of fifty episodes, making it the longest season to date. The first half of the season is included within the season 9 DVD box set, which was released on April 3, 2001, and the second half is included within the volume 6 DVD box set, which was released on April 3, 2001. Volume 6 was split into seasons 7 and 8 in regions outside the United States, leading to confusion over season numbers between U.S., Australian, and UK consumers. 
Hellstorm's Files had been ended in 1987 due to low ratings, but was revived by Network/Warner after reruns on WTBS Superstation became the network's most-watched program, and more than three million DVDs of the show were sold. "Welcome Back, Winsconsin" was the first episode to air following the series' revival.
The executive producers for the fourth production season are series creator James O'Connor, along with David M. Harber and Frank Taylor Smith. Starting with this season, O'Connor would hand over showrunner duties to two writers, with Harber and Smith being the inaugural co-showrunners.
