The Official Big Bang Theory Podcast has returned to revisit Seasons 3 and 4 of The Big Bang Theory, and this time the podcast is presented in video.

Hosted by Jessica Radloff, author of the New York Times bestseller The Big Bang Theory: The Definitive, Inside Story of the Epic Hit Series and the upcoming Young Sheldon: The Inside Story of the Hit Comedy, the podcast takes a look at a classic TBBT episode each week. Radloff is joined by a special guest - from cast members and guest stars to writers, producers and crew - to share behind-the-scenes stories and memories from the show.

For its new episodes, the podcast has moved to a purpose-built video set from HBO Max and Warner Bros., allowing fans to watch Radloff and her guest of the week as they discuss the episode and react to clips from the show.

The podcast originally launched in March 2025 with a look back at the unaired Pilot, which was developed for the 2006/07 season, before continuing through December to cover all seventeen episodes of Season 1 and all twenty-three episodes of Season 2.

Guests during the first two seasons included The Big Bang Theory co-creator Chuck Lorre, executive producer Steven Molaro, director Mark Cendrowski, cast member Kunal Nayyar, future cast member Kevin Sussman, and guest stars including Sara Gilbert (Leslie Winkle), John Ross Bowie (Barry Kripke) and Christine Baranski (Beverly Hofstadter).

In a recent Instagram post, Jessica Radloff teased several upcoming guests for the new season, including The Big Bang Theory cast members Kunal Nayyar, Simon Helberg, Mayim Bialik and Melissa Rauch. Other guests set to appear include guest stars Joshua Malina (President Siebert), Brian Thomas Smith (Zack), Wil Wheaton (himself), executive producer Steve Holland and Young Sheldon star Raegan Revord.

In the first episode of the new season, Jessica was joined by showrunner and executive producer Steve Molaro to discuss the Season 3 premiere, "The Electric Can Opener Fluctuation", which saw Leonard and Penny finally get together. Molaro discusses why the writers chose not to drag out Leonard and Penny's long-awaited move from friends to something more, and why they decided to make the couple's first night together less than perfect. He also reflects on how Kaley Cuoco and Johnny Galecki's real-life relationship at the time helped shape the chemistry fans saw on screen.

The Official Big Bang Theory Podcast is released every Monday on HBO Max and all major podcast platforms, including Amazon, Apple, Spotify and YouTube.
