The usenet provider Giganews announced today that they would increase the retention of all binary newsgroups to 100 days over the next two weeks. If you never have heard about the usenet before let me explain the concept with just a few words. The usenet can be divided into binary and discussion groups. Thousands of binary groups for every purpose, from mp3 to movie to games exist and every user who has usenet access is able to download all the files that get posted to the usenet daily.
