FXX debut 'The Simpsons' with 12-day, 522-episode marathon in August 2014

The Simpsons is headed over to a new network, FXX, for syndication and to properly celebrate we're getting a 12-day, 522-episode marathon!  

Jon Landgraf, chief executive of FX Networks, announced this big news this week at an upfront presentation.

"It will be the longest continuous marathon in the history of television," he exclaimed.

"Think of it as a comprehensive, beautifully curated digital library of all things 'Simpsons,'" Landgraf said. "I'm absolutely blown away by what I've seen. This could well be the best app I have ever seen."

Variety reports:

There's reason to give Bart, Lisa, Maggie and the rest a big push. Sale of the series to FXX was valued at more than $750 million over the life of the deal - an astronomical price for syndication. The terms of the pact includes making the vast "Simpsons" archive available via video on demand on the FXNow viewing app. The show has never before been available in wide fashion online or on any SVOD venue.

Landgraf said the unit, which comprises FX, FXX and FXM, would raise the number of original series across FX and FXX to 20 from 11. Among the series slated to debut in coming months are "The Strain," a sci-fi horror series based on work from Guillermo del Toro, author Chuck Hogan and writer-producer Carlton Cuse; "Tyrant," a drama set in the Middle East supervised by "Homeland" producer Howard Gordon; "The Comedians," featuring Billy Crystal and Josh Gad: and comedy series for FXX starring Tracy Morgan that will have long-running "It's Always Sunny in Philadelphia" as its lead-in.
