Pre–World Wide Web online services areonline service providers that predate the creation of the world wide web in the early 1990s and did not (initially) useTCP/IP. They were accessed directly over the phone line or via a time sharing network likeTymnet by use of amodem instead of over theinternet. They mostly disappeared after 1995 as theinternet grew to widespread use. Some services, such as Delphi, AOL, and CompuServe were able to transition their offerings to internet-based formats. They existed alongsideBBSes but represent a more commercial edge of the spectrum, in contrast to the hobbyist/local nature of a BBS.[1]
