Unlike the last live stream Apple did, this time around Apple decided to add some JSON (JavaScript Object Notation) code to the page which added an interactive element on the bottom showing tweets about the event. As a result, this was causing the page to make refresh calls every few milliseconds. By Apple making the decision to add the JSON code, it made the website un-cachable. – Streaming Media

The stream was a complete mess yesterday. I hope I’ll find the time today to rewatch it because what I saw yesterday was: a phone, a watch, and yellow emoji’s.
But almost no context or story. Hope the second view is better.
