Dvd players have been declining for years. recognizing that dvd players are a thing of the past, those who manufactured dvd players have not attempted to make any changes but are letting them live out the remainder of their lives. the makers of dvd players have new technology to explore and do not want to waste resources trying to prolong the life of an obsolete technology. this is an example of

A phase-out.

Explanation:

This means to stop using something which has reached the end of it's functional lifespan. DVD players became obsolete (because new technologies became available) so it's makers decided to explore new alternatives.

This is called decline (or decay) phase which is when the utility and potential value in producing and selling the product begins to drop. This decline eventually reaches the point of zero (which is when the "phase-out" begins).
