The program was aired on Tuesdays in all of Radio Sweden's services (i.e. languages) except Swedish.
After a number of years, as media changed, it began to cover less about shortwave, and more about satellite radio and television.
Later coverage was extended to the Internet, the focus was shifted to concentrating on Swedish media, and the name of the English version of the program was changed to "MediaScan".
"MediaScan" was the first English language radio program in Europe (and the second overall in Europe) to post audio on the Internet (on the ftp sites ftp.funet.fi and ftp.sunet.se, as well as via Internet Multicasting), starting in 1994.
The original Sweden Calling DXers bulletins were replaced by the MediaScan Online Edition, which remains in a somewhat sporadic form on the Radio Sweden website.
