Released in April 1976, selling at an MSRP of $1095.
Quiz Show is believed to be the first game to utilize the now well-known 'arcade font' (formerly thought to have been first introduced with Sprint 2 or Cannonball, but Quiz Show predates these two games by six months). This font is likely to have been designed by Lyle Rains and has since been used by many non-Atari games manufacturers including Namco, Irem, Nichibutsu, and Nintendo.
As you can see in the description, Quiz Show contains a total of 1000 questions and 4000 possible answers.
