Benny began taking people on tours of historic sites in his town. he started to make a nice profit with the tours, particularly with tourists passing through the town on the way to the mountains. benny began to hear of some rival tour groups that were planning to start giving tours in the area. benny sent a memo to his secretary asking, "how can we shut down other potential tour groups because we want all the business? " one rival company had started operations, but benny still had 85 percent of the business. his plan was to run the rival out of business and prevent the start-up of any other tour operations in his town. benny decided that he would offer to do a free advertising brochure to any business that would put up a poster advertising his tour group and agree not to advertise or mention in any way any other tour group. benny was particularly successful in reaching that agreement with hotels and restaurants in his town because of his likeable personality and the business that he began referring to those specific hotels and restaurants. when james, who ran a rival tour group heard about benny's actions, he was furious and accused him of an antitrust violation because he was trying to keep all the tour action for himself. what must be proven against benny in order to establish that he violated antitrust laws through conduct involving monopolization?
