The Penguin Hotline, Penguin Random House’s holiday gift-giving book recommendation service, completed its ninth season in December. The Hotline is completely free and easy to use: Consumers can write in to www.penguinhotline.com and answer a few questions about the people they are buying holiday gifts for, including the readers’ favorite books, TV shows, movies, magazines, hobbies, etc. Within a few days, the consumer will receive a personal letter from a PRH employee with customized book recommendations to help them shop. The Hotline runs for two weeks every holiday season.
