MT-NewsWatcher is a Usenet news client for the Macintosh. Usenet is a globally distributed news network over which many thousands of people distribute messages every day, and which contains discussion groups on virtually every topic under the sun. MT-NewsWatcher allows you to quickly and efficiently target the articles you wish to read, with sophisticated yet easy to use filtering, searching and sorting features. The program also makes viewing and saving binaries from newsgroups easy, and works transparently across multiple news servers.

MT-NewsWatcher is derived from an earlier program called simply "NewsWatcher", by John Norstad of Northwestern University, but greatly enhances that program's feature set.
