The Grateful Dead’s farewell shows in Santa Clara and Chicago drew a crowd of over 350,000 to the locations themselves, but that audience becomes even bigger when you factor in the pay-per-view audience that couldn’t physically be at the concerts but still wanted to take part in the experience.

A new report from Billboard says that it was the most-watched PPV music event ever, with the five-night broadcast of Fare Thee Well: Celebrating 50 Years Of Grateful Dead pulling in more than 400,000 buyers through either cable/satellite subscriptions or online streams. And considering that a lot of those buyers in turn held gatherings at bars, theaters, and households, the number of people who actually watched the concerts is much larger than that.
