Jellyvision's YOU DON'T KNOW JACK® is truly a unique interactive experience, one in which the illusion of awareness on the part of the program creates the sense of a conversation between user and host. With massive branching scripts and prerecorded audio files programmed to play in response to specific user input, YDKJ allows users to forget that they are interacting with a machine and feel like the character in the computer is "talking" to them.
In other words, YOU DON'T KNOW JACK is the perfect example of what an Interactive Conversation can accomplish.
Way back in the early-90s, Jellyvision decided to test the waters of mainstream interactive entertainment by beginning a partnership with Berkeley Systems, of "Flying Toasters" fame. Berkeley Systems asked us if we could apply the concepts of a game show to an adult trivia game. Since no one at Jellyvision at the time actually liked trivia games, we tried to figure out how to make trivia questions fun and engaging to us. When we realized that it was possible to ask about both Shakespeare and Scooby Doo in the same question, YOU DON'T KNOW JACK was born.
Released in the fall of 1995, YDKJ became an instant best-seller and redefined the trivia game market for adults with its direct-response interactivity and snarky fusion of high culture and pop culture. In 1996, the company's name was changed to Jellyvision in response to the expansion of product lines beyond its early educational focus.
Jellyvision's YOU DON'T KNOW JACK franchise now includes well over a dozen products, including 10 CD-ROMS, two PlayStation titles, a tabletop version, two books, a daily online game and numerous foreign language versions. YDKJ even spawned a TV show, starring Paul Reubens, that aired on ABC during the fall of 2001. With over 4.5 million units sold, more than $100 million in revenue, distribution in five countries and over 50 major industry awards, YDKJ is one of the most successful gaming franchises ever
With the popularity of the YOU DON'T KNOW JACK franchise came an explosion in interest from others to apply the same principles that made the games so engaging to their own businesses. This spawned the creation of the Jack Principles of the Interactive Conversation Interface - Jellyvision's how-to handbook of interactivity - and inspired the company to move beyond the world of gaming, in order to forge a new approach to interactivity, leading to higher ROIs and conversion rates.
