CBS News has done something interesting on it's website.
You can go to http://www.cbsnews.com/stories/2011/04/06/broadcasts/main20038288.shtml?tag=cbsnewsTwoColLowerPromoArea
, and download both the current (2000-present) or the classic 1983-2000 CBS News sounder used at the beginning of the network's hourly radio newscasts.
Fans of classic radio might be interested in downloading the 1980's/1990's sounder as a ringtone.
I wonder if CBS might also make available the 1968-83 hourly radio news sounder (the first to use the five notes at the beginning) as a downloadable ringtone.
I don't work for CBS or any of it's subsidiaries, but I thought this was interesting and worth sharing.
