Radio Station KSCS broadcast a popular music program. It announced that it would pay $25,000 to any listener who detected that it did not play three consecutive songs. Steve Jennings listened to and heard a program in which two songs were followed by a commercial program. He claimed the $25,000. The station refused to pay on the ground that there was no consideration for its promise to pay that amount. Was the station liable? [Jennings v Radio Station KSCS, 708 SW2d 60 (Tex App)]
