YouTube is a vital online platform and a huge player in the attention economy. But it wasn't always a billion-dollar platform for daily vloggers, podcasters, gamers, and more.

Mark Bergen, technology reporter at Bloomberg, recently wrote a book called, Like, Comment, Subscribe: Inside YouTube's Chaotic Rise to World Domination, and he joins us to discuss YouTube's relationship with Google, the behind-the-scenes of how it became so popular, and how YouTube has affected how we use the internet today.
