==Explanation of Edits== 

 I have noticed there is a high amount of adding and removing of programing, and whenever it is changed from what some believe is the "correct" programming, it is marked as vandalism and reverted.  I just want to explain why I edited what I did today - I removed Inside Out Boy and Hey Dude and inserted Secret World of Alex Mack.  This edit is not just because of what I think should be on the show, but is properly referenced to a Washington Post article, which is considered a reliable source.  

 Now, in the description before the episodes, it says not to edit without a reliable source, which I have, but also says that the shows are on the list because "they are in the commercial".  I don't think the commercial alone is a reliable source - shows occasionally put something in a commercial that does not end up airing (Make It or Break It is notorious for doing this).  Plus, there were no clips (in the three commercials I saw) for Hey Dude!  I'm not sure about Inside Out Boy.  Either way, the list I have gathered from Washington Post, the schedule that Nickelodeon themselves confirmed, is as follows: 

 Aaahh!!! Real Monsters  
 The Adventures of Pete & Pete  
 All That  
 The Amanda Show  
 Are You Afraid of the Dark?  
 Catdog  
 Clarissa Explains it All  
 Double Dare  
 Doug  
 Hey Arnold!  
 Kenan & Kel  
 Legends of the Hidden Temple  
 Nickelodeon GUTS  
 The Ren & Stimpy Show  
 Rocket Power  
 Rocko's Modern Life  
 Rugrats  
 Salute Your Shorts  
 The Secret World Of Alex Mack  

 Now, this can change, and might change, but at this time, it is the confirmed list of what will be aired during the block.  Reference/citation is http://live.washingtonpost.com/nickelodeon-brings-back-90s-shows.html. 

 Also - you should check out that reference after tomorrow - the Senior Vice President and General Manager of Nicktoons and TeenNick Keith Dawkins will be answering fan questions and comments live on this article.  This should help clarify what will and won't be part of this block.  There will probably be a lot of people editing this page tomorrow, because of this, as well.
