X*PRESS Information Services, Ltd. was a partnership between McGraw-Hill and former cable television giant Tele-Communications, Inc. (purchased by AT&T Corporation and later spun off).
Data included delayed stock ticker quotes and news headlines from the Associated Press, Agence France-Presse, McGraw-Hill, Standard & Poor's, Reuters, and UPI.
Specifically, the system's data stream was carried on C-Band satellite onboard CNN's (later WGN's) transponder using General Instrument (now part of Motorola) InfoCipher 1500P satmodem technology.
Sometime in the 1990s, the X*Press X*Change service was renamed InGenius, and faded into obscurity shortly afterward with the rise of the modern Internet as well as improved cable television on-screen graphics technology.
This effort was helped by the fact that the Amiga version of X*Press X*Change was distributed on a floppy disk that had, by mistake, some random portions of the software source code on some of its unused blocks.
