How famous are you, when you get right down to it?

Do you have a couple dozen followers on Twitter? Some subscribers to your YouTube channel? Or are you actually known worldwide, even if it’s in a niche way?

However famous you are - even if you’re not Jennifer Lawrence or Beyonce (though it would be very cool if you were) - we hope you enjoy this week’s show, which is all about fame, celebrity, and what it means now.

First up, there are few people more famous - at least among the NPR set - than Yo-Yo Ma. Master cellist, collaborator with the Dixie Chicks, and one of the performers behind The Goat Rodeo Sessions, Yo-Yo Ma seems like he’s been everywhere and done almost everything. He shares his thoughts with Kara about creativity, music, and the German word for butterfly.

So, how does a musician become famous? There’s promotion, practice, social media, touring, and now… TapTape. Chris Nolte explains how this new marketplace, where fans can support musicians, could change the music industry.

Then, have you heard of PewDiePie, Michelle Phan, or Shane Dawson? Well, they’re YouTube stars, and they’re some of the most famous people in the world. Variety’s Andrew Wallenstein and Tubular Labs’ Allison Stern take us into the new world of celebrity, and tell us why the Internet is the new Hollywood.

And finally, if you think that our celebrity culture is a new thing, think again. In the 19th century, women sent Lord Byron (yes, the poet) locks of their own hair… and not just from their heads. Historian Sharon Marcus dives into the history of fame and celebrity, and tells us who the Angelina Jolie of the 1860s was.
