Jason Kelce believes his "loving relationship" with his brother Travis is the key to the success of their podcast series

Jason - who announced his retirement from the NFL earlier this year - said during an ESPN media day: "I think on the podcast, you get, first of all, an organic, loving relationship between two brothers. We're honest with each other. And it comes across.

"And we have good personalities that I think generally audience members appreciate, and like to want to watch and listen to, which I don't know if I agree fully with that, but they're there."

Jason also observed that he and Travis - who began dating pop star Taylor Swift in 2023 - are both "very open people".

He explained: "I think that we're very, very open people by nature, and I think that we share things, and we obviously are living exciting lives that people want to follow. And then all that stuff helps ... because the more people watch, the more money advertisers spend."

Travis and Jason recently signed a nine-figure deal with Wondery for their 'New Heights' podcast.

Jen Sargent, the CEO of Wondery, told The Hollywood Reporter: "We've been watching the growth of the podcast, really since it was launched, and I have been building a relationship with Travis and Jason and getting to know them for a while now.

"Sports is a really exciting category for podcast listeners. It's a strategic priority of Wondery's and Amazon's. So there were a lot of reasons to think about joining forces here on the 'New Heights' podcast."
