Question about Casey Kasem's old AT20/AT10 show's.

I was just curious where Casey got the Digital Download and Album chart info for his show's. Normally, when Casey announced the top's of the other chart's he also announced the Digital Download and Album chart #1's. I looked up on Mediabase but they don't have those chart's listed. Unless for the Album chart he used the Triple A chart? If you know where Casey got these 2 chart's and where I can find them let me know, thank's! :)

Wouldn't he have just used Billboard or Soundscan? Or was this before Billboard started tracking digital downloads? The days of Casey seem so long ago. :(

That would make sense but Casey hasn't used Billboard on his chart's since 1989 when he switched to Radio and record's, then it was Mediabase 24/7 he used in the final day's. I am thinking that the Digital Download chart may not be a published chart?
