On this edition of Business Weekly, we look at the battle between the makers of one of the world’s biggest computer games, Fortnite, and the world’s biggest tech company, Apple. The court case could have implications for how app stores and payment models are run in the future. We also take a look at the jewellery sector and hear two different tales of sustainability - from those selling diamonds made in a laboratory and those digging them out of the ground. Plus, we head to campuses in the United States, where universities cash in on the popularity of college sports, while the players themselves - the students – rarely see a penny for their efforts. That is quickly changing, but perhaps too rapidly for some observers. Business Weekly is presented by Sasha Twining and produced by Matthew Davies.
