Digicel аnd Atlаntic Tele-Netwоrk (ATN) аre duоpоlies in the Bermuda telecommunications market. They are fierce competitors. Digicel is considering introducing a new protocol that would make messaging (text, voice and video) easier for Digicel and all other smartphone users. ATN has a similar idea of introducing a new messaging protocol. It makes no sense for either telecommunications firm to introduce its protocol without first getting the other company to accept its protocol. It's too expensive to use both protocols. If Digicel introduces its protocol and ATN accepts, then both firms will earn a profit: Digicel will make $120m and ATN will make $100m. If however, ATN introduces its own protocol and Digicel introduces its own as well, then both will lose $50m.
