HQ Trivia presenter: We changed people's lives

The real-time quiz app HQ Trivia has shut down.

In 2018 people would gather around a phone to take part in the daily quiz, with estimates suggesting there could have been 2.3 million people playing the game at the same time.

But now the app has run out of money.

Back in 2018 Sharon Carpenter told the BBC she believed HQ Trivia and its format was "the future of television".

What does she think now? BBC OS has been speaking to her.
