YouTube at 15: The video platform has revolutionized the way we consume content online — but at what cost?

YouTube has revolutionized the way we interact with videos online. It's changed the way we search for content, listen to music and learn new things, and it's created a space for emerging artists to bypass the gatekeepers — but at what cost?

The video streaming platform launched 15 years ago today. It now hosts more than five billion videos with more than two billion people using the site every month, but along the way things have become complicated. From algorithm changes to the burnout, anxiety and financial instability that comes along with making it as a YouTuber, the platform has had its share of challenges over the years.

On YouTube's 15th anniversary, culture writer Alyssa Bereznak and YouTuber turned filmmaker Joe Penna joined q guest host Laurie Brown to take a look back on the highs, lows and major changes that have come to the platform over the last decade and a half.
