mercredi 19 janvier 2022 • Duration 29:50
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.

mercredi 1 décembre 2021 • Duration 29:51
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?

It’s Not TV: Behind HBO’s legendary sounds
Episode 136
mercredi 17 novembre 2021 • Duration 27:48
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.
