Here is a list where you can find the original sources of much of the information on the anniversary site. Please visit them and enjoy the rest of their work. Many thanks to their webmasters!!!!

  • When this site was created in 2000, the midi files and news headlines were taken from various sites around the internet. Unfortunately, as of 2006, these sites are no longer available.  Here is a list of the sites as a reference:
  • All of the 1970s news headlines and midi files came from  "Totally 70s Site"
  • All of the news headlines from the 1980s and 1990s came from a "Teachers' Resource Site"
  • All of the 1980s midi files came from a site in Singapore.
  • All of the 1990s midi files came from the "Hot Midis" site
  • The circa 2000 AT40 logo was found on the AMFM site when that site existed.
  • The modern era AT40, AT20, and AT10 logos are from Premiere Radio Network site.
  • The news headlines from the 2000s came from the infoplease website.
  • Special thanks to the former American Top 40 Celebration Page for their help with: All of the AT40 specials information, AT40 chart information from 1970-1995, AT40 graphics from 1970-1988, and all of the jingles.
