They are different and not one

eGroups.com was an email list management web site. The site allowed users to create their own mailing lists and allowed others to sign up for membership on the list. The web site provided archives of the messages as well as list management functionality. Each group also had a shared calendar, file space, group chat, and a simple database. It was bought by Yahoo! and became part of Yahoo! Groups.

Same as forum, an on-line discussion group. On the Internet, there are literally thousands of newsgroups covering every conceivable interest. To view and post messages to a newsgroup, you need a news reader, a program that runs on your computer and connects you to a news server on the Internet.
