Over the last several years, Apple has gradually been expanding the ways people can tune into its various keynotes. This year, Apple is further expanding its efforts and will stream the September 10th iPhone 11 event on YouTube.
For those with long memories, for a long time the only way you could actually stream Apple’s events was through Safari and/or an Apple device, and then Microsoft Edge. Grabbing the direct stream via something like VLC was possible but required a level of technical know-how; expanding to Youtube dramatically boosts the potential audience for this. A fun little historical footnote on the slow trend of a far more open Apple under Cook.
