Jellyvision is a multimedia production company best known for making the You Don't Know Jack games. Originally named "Learn Television," it produced a number of edutainment titles, such as "That's A Fact, Jack!", before branching out into pure entertainment multimedia. At that point, the company name was changed to "Burnt Jellyvision" (a form of their original name, as would be used in a You Don't Know Jack 'Gibberish' Question), but the company quickly decided to just use "Jellyvision."
Jellyvision now has two distinct business groups - Jellyvision Games, since split off into its own company and rebranded as Jackbox Games, which continues to produce multimedia games such as You Don't Know Jack and The Jellyvision Lab, which creates Interactive Conversations for Fortune 500 companies and ALEX, an interactive application that teaches employees about choosing a healthcare insurance plan, saving for retirement or managing finances.
