Thanks to Bart, Homer, Marge and the Springfield gang, FXX has become the network that grew big-time. The 12-day marathon of The Simpsons on the cable network saw all 522 episodes of the 25 seasons of the show — plus 2007’s The Simpsons Movie — airing in a row starting August 21. It also saw massive gains for the comedy-based, year-old channel, which catapulted up 658% over its previous primetime average in the adults 18-49 demo to take the top spot among basic cable networks.

The 12-day primetime average in the key demo was 841,000 viewers – a lot more than the 111,00 the channel averaged pre-marathon. In total day, FXX had 633,000 in the demo – a 1,030% launch over the 56,000 it had in 18-49s before the marathon started. To put it in further perspective, FXX had been No. #49 in primetime among its basic cable competitors. With the marathon, it was No. 1 among adults 18-49 in cable networks in primetime. That even topped mighty ESPN’s 815,000 in the demo.

The top episode of The Simpsons marathon was “The Man Who Grew Too Much.” Airing on the September 1 Labor Day holiday FXXat 7 PM, the 2014 episode was No. 1 in both the 18-49 demo with 1.43 million viewers and in total viewers with 2.22 million. The episode featuring Sideshow Bob was the 543rd episode of The Simpsons and first aired this year on March 9. In fact the holiday was very good to The Simpsons on FXX: The second and third most popular episodes of the marathon were also on Monday evening with Episode 542 “Diggs” at 6:30 PM coming in at No. 2 with 1.35 million in the demo and 2.18 million total viewers, and Episode 541 “Specs And The City” at No. 3 with 2.14 million total viewers and a 1.3 in 18-49.

I do agree that the quality of episodes past S11 aren't all bad, but I don't agree...

WHY YOU LITTLE! I love the Simpsons, but, I just can't stomach the new episodes past season...

In terms of overall viewers, the marathon pegged FXX in the No. 9 spot in primetime with an average of 1.322 million. That 542% leap was better in terms of total day by a 855% upward movement to 955,000 viewers on average. In total day viewership, FXX became the No. 7-rated basic cable network over the 12 days.
