Murdoch Buys Delphi -- Speaking of the net community, it gained a new mogul recently. The News Corp., a company owned by publishing magnate Rupert Murdoch, has purchased Delphi, which now claims to be the fifth largest commercial online information provider behind CompuServe, Prodigy, GEnie, and America Online. Delphi is the only major information service fully on the Internet, and it seems likely that many of the newspapers and magazines under Murdoch's control will eventually appear on the Internet. Of course, such a possibility raises questions about the survival of current free electronic publications, although we have some ideas percolating.
