Usenet Newsgroups are for a discussion on a particular topic, or for you to read or post a piece of information and, of course, the readership of a newsgroup is potentially worldwide.
There are a large number of newsgroups, each one acts like a bulletin board or notice board, covering a particular topic. The messages in newsgroups are similar to email but messages that are sent may be read by anyone and we can all choose whether or not we wish to read it or reply to it. Replies may be placed on the newsgroup or they may be directed to the author as email .
To use newsgroups directly from a browser then this can be done through Google.com .
