S. movie industry, where the so-called blockbuster strategy is causing movies to open with big tallies that fall off faster than in previous years. Movie ticket sales reached an estimated 8.35 billion in 2001, up 8.4% from 7.7 billion in 2000, the largest gain since 1998.

B. the studios gain most of the ticket receipts while the theater operators gain less.
