Before Radiolab became a cultural phenomenon, it was an experiment… one that Jad Abumrad built voice by voice, sound by sound. In this episode, Jad walks Dallas through his journey with the show, from its scrappy beginning in a New York basement, to leading a massive team, and ultimately stepping away. Along the way, he breaks down his signature sound design and storytelling techniques, and how he’s carried those into newer projects like Dolly Parton’s America and Fela Kuti: Fear No Man.

When The Sims was first being developed, the creators faced a problem. They knew they wanted these characters to talk and interact, but they were worried that using a real language would quickly get repetitive and annoying. So, they decided to make one up. This is the story of Simlish: How it was created, why it works so well, and why artists ranging from The Black Eyed Peas to The Flaming Lips have re-recorded their songs in this gibberish language.

In part 2 of our series on HBO, we explore the tough questions that the company faced in the digital era: Are people still willing to sit through a 90-second theme song before they watch a movie? Does the sound of analog TV static even make sense to younger viewers? Could the company change with the times without losing the nostalgia they had built around their key sounds?

In the 1980s, every movie that aired on HBO began with a truly epic theme song—a sweeping orchestral piece that triggers instant nostalgia for anyone who grew up with it. Then in the 90s, HBO introduced a 5-second audio logo for their original content. Today, we associate that sound with some of the most groundbreaking TV shows of all time. In this episode, we reveal the story behind the creation of these two iconic sounds. Featuring composer Ferdinand Jay Smith and former HBO Executive Vice President Bruce Richmond.
