The marathon has been gaining steam and viewership through the first six days of its 12-day run, and has led FXX to rank as one of the top five basic-cable networks each night, the site notes.
The Simpsons will air on FXX on Mondays from 6 p.m.-midnight, Tuesdays from 8 p.m.-midnight, Thursdays from 8 p.m.-midnight, Fridays from 6 p.m.-midnight; and Sundays from 4 to 8 p.m.
