Here’s as exhaustive a list as we could muster of the alliances, business agreements and shared financial interests of companies involved in the nascent interactive TV/interactive services industry. All things considered, this list is probably already out of date.

The more important question is what significance do any of these cooperative arrangements have in a world where Cablesoft exists? As TCI chairman John Malone said in a recent magazine interview, “When you’re driving plate tectonics, you’re going to squeeze people’s tails.” We bet the people on this list wish it was only their tails getting squeezed. We predict that in the next six months, many of these alliances will be materially altered as a result of Cablesoft, even though it will be years before a full-service network is actually operational.
