Tony: A new kind of videocassette has just been developed. It lasts for only half as many viewings as the old kind does but costs a third as much. Therefore, video rental stores would find it significantly more economical to purchase kind of videocassette than on the old kind.
Anna: But the videocassette itself only accounts for 5 percent of the price a video rental store pays to buy a copy of a movie on video; most of the price consists of royalties the store pays to the studio that produced the movie.
