This week, Marc Fennell dropped by the Mumbrellacast to talk about his latest podcasting venture with Audible, Nut Jobs. He describes his adventures in the USA to explore the illegal nut trade, explains Audible's interest in storytelling, and ponders if there really is a podcast for everything?

Over in adland, a couple of big leadership changes took place. Wunderman Thompson CEO John Gutteridge announced he was stepping down with Lee Leggett taking over. Gutteridge was the last WPP AUNZ CEO to oversee one of its famous creative agency mergers, closing another chapter in the holding group's saga. The team also analyses the slow introduction of a new leadership team over at Clemenger BBDO Melbourne.

The week in media saw News Corp announce the closure of women's content network Whimn. Was it purely a branding decision? Or is this the latest cost-cutting measure? This was soon followed by a slump in readership of news.com.au and the ABC firmly holding first place. And, how did the first weekend of the NRL fare in the TV ratings?

Also, ahead of its return to Australian screens on Monday, Sonia Kruger spoke with Mumbrella's Vivienne Kelly about the new-look Big Brother. What kind of housemate would Kruger be? And what's it like facing a COVID-19 scare on set?
