Answer:
Cooperation with competitors.
Step-by-step explanation:
The companies are direct competitors in a market that is fast-moving such as the Blu-Ray market. As a result, the companies have to introduce innovations and improve customer experience in order to stay afloat, otherwise, the customers will turn to the competition.
In this case, the competitors decided to cooperate: their goal is to bring about a product that is more innovative, and provides a better customer experience, as a result of the different inputs from each of the competing companies.
