What is PROJECT MASSIVE?

 A letter writing campaign to prove that it is not "too expensive" to make new episodes of Invader Zim.

• The show's creator "would love to do more Zim stuff" (source)
  
• New episodes were almost greenlit in 2010 
  (see previous source)
  
• It was likely cancelled over "ratings and sheer expense"  (source)
  
• Nick mentioned "Operation Head Pigeons"-- who publicize this (source)
  
• Censorship on Zim was never Nick's concern (source)

• All updates will be found here and its blog page.

THE PLAN:

Thousands of fans will each write a (polite) letter to Nickelodeon all at once.  Address available at project-massive.com

Who was behind this?: Operation Head Pigeons joined forces with Invadercon staff to organize this letter writing campaign.  More recently, OHP gained more control of the reigns rather than being mere publicists.  The campaign kicked off at Invadercon II: Doomcon.  Toys of Hope charity was benefited in lieu of the sentimental items typically sent to studios during letter writing campaigns.  

DO NOT DEFY HIM.
