See Web browser.
browsern. A program specifically designed to help users view and navigate hypertext, on-line documentation, or a database. While this general sense has been present in jargon for a long time, the proliferation of browsers for the World Wide Web after 1992 has made it much more popular and provided a central or default meaning of the word previously lacking in hacker usage. Nowadays, if someone mentions using a `browser' without qualification, one may assume it is a Web browser.
