Question: Person1: Did you hear the news ? Two of our major suppliers , Murphy Music and U-Tunes are merging ! If they are conglomerated into one company into one company , it would have some serious affects on our market strategy .
Person2:Are you sure ? Who told you that ? I highly doubt that they would take the step to merge into one company ... They're supposed to be bitter enemies , the strictest of competitors.It must be a rumor.It can't be true .
Person1: I read it myself on the financial page.They ' re really going to join together . U-Tunes was bought out by Murphy's , they will take over the company as of next month .
Person2:The competition must have been too stiff for U-Tunes.Otherwise why would they allow themselves to be taken over by their sworn enemy ?
Person1: I guess they must have figured it would be easier to merge than to keep up the cutthroat competition.If you can't beat'em , join'em .
