Questions about This Site
don't you place the current Top 20 or Top 10 chart, as well as
an archive of past charts?
The problem is that the charts are copyrighted.
If I posted them without permission, I would be in violation
of copyright and would be open to legal action. I believe that
is what happened to the "Casey's Top 40" site at charter.simplenet.com.
Both R&R and Mediabase's charts are copyrighted.
don't you have any pictures of Casey Kasem on your site, or for
that matter any official AT20/AT10 logos?
I do not for the same reason I do not
place the charts on the site, copyrights. I believe that most
pictures of Casey are copyrighted. The same is true for the logos.
Thus my site may not look "official", but it is legal.
:) An example of what can happen for using copyrighted images
is what the parent company of Star Trek did to fan sites. If
a fan had copyrighted images, sounds, etc. then they were pursued
by the legal department and had to change their sites or even
had their sites removed.
often is this site updated?
I try to update this site every Sunday.
The list of number ones, as well as the trivia sections are updated
weekly. Of course, the updates may be delayed if my schedule
"Can you please add AT20/AT10 to my (state, country).
We can't hear you anymore..."
"Can you please change such-and-such on your show..."
I have no control over who can hear
AT20/AT10. If you want to hear AT20/AT10, contact your local
radio station. Also, I am not affiliated with AT20/AT10
in any way. I'm just a fan like you.
Questions about AT20
2. When did AT20 begin? When did AT10 begin?
Some important dates in AT20 history are:
- 1992 - Casey's Countdown, an AC show, debuts
- November 5, 1994: Casey's Hot 20 debuts
- March 28, 1998: Casey Kasem moves to AMFM Radio Networks
(which will eventually be bought by Premiere). Casey's Countdown
becomes American Top 20 AC, while Casey's Hot 20 becomes American
Top 20 Hot AC.
- January 10, 2004 - Casey leaves AT40, making his only shows
the 2 AT20s.
- March 20, 2004 - AT20 AC becomes AT10.
2. What charts have AT20/AT10 used during their run?
Casey's Countdown used the Radio and Records' AC chart. Casey's
Hot 20 used the R&R Hot AC chart. When the shows became AT20,
they continued to use the R&R charts. During a period from
2000-2001 the shows switched to an unpublished chart. In August
2001, the shows switched back to the R&R chart.
In early 2003, AT20 AC switched to an unpublished Mediabase
24/7 chart, which was based on audience rather than the number
of times a song is played, and excludes all audience numbers
from the songs played during the syndicated "Delilah"
show. AT10 switched back to the R&R AC chart in 2005.
In August 2006, Radio and Records was bought out by the parent
company of Billboard Magazine. Therefore R&R quit using Mediabase
data and started using BDS data. AT20 and AT10 continue to use
the Mediabase 24/7 charts, which are not published in a major
trade magazine at this time.
3. Why did songs frequently fall off the current chart
from the teens?
Songs are removed from the chart to "recurrent"
status. On the Hot AC show, songs are removed when the song falls
below #15 and has been on the entire Hot AC chart for more than
20 weeks. The AC chart has the same rule as stated above, but
has another one as well. Songs are removed from the AC chart
if the song has more than 50 weeks and is below number 5.
