AT&T Corp is most at home with what is contemptuously dubbed POTS for Plain Old Telephone Service, and its preference is being carried over into the on-line services and Internet access arena. Starting about four years ago, the company assembled a large portfolio of high value added network services, but one by one, these have all been dismantled or sold, and very soon it will be left with nothing more than Plain Old Internet Access. Latest to go is the ImagiNation Network Inc, which is going to the lustiest surviving bastion of proprietary on-line services, America Online Inc, Vienna, Virginia. The ImagiNation Network enables games enthusiasts to play each other on-line. AT&T acquired ImagiNation Network in 1994 for $40m, but admits it has been losing money on the busines, and America Online is thought to have paid less than $40m. ImagiNation, Burlingame, California will migrate its users to the America Online Games Channel as it discontinues support for its MS-DOS-based games service.
