Audiences of WGBH’s High School Quiz Show can now play against Massachusetts whiz kids through an online game that launched early this month. The Boston station’s digital team developed a browser-based game allowing viewers to play along during broadcasts of High School Quiz Show. The game is based on a technology that has become popular among quiz shows in England. The High School Quiz Show live game is running in its beta version, and will be available through the season’s championship episode, to be broadcast May 19. WGBH developers are testing the game on a total of eight shows this season, according to Hillary Wells, e.p. of children’s programming.
