Firms 1 and 2 simultaneously and independently select to adopt
either technology A or B. Technology A is regarded as superior by
both firms, yielding a payoff of 2 to each firm if they both adopt

payoff of 1 for each. If they do not adopt the same technology,
both obtain a payoff of 0 (because consumers will not want to have
to convert files between the two technologies).
