This morning, a user on Reddit pointed out that the ‘EveryAppleVideo’ YouTube channel has been taken down. Visiting the channel page takes you to an empty channel under a banner reading ‘This channel was closed and is no longer available.’ without any additional explanation.
The channel was well known for its collection of over a thousand Apple ads, keynotes, and other videos dating back to the 1980s. It was basically the ultimate archive of every Apple video that ever existed.
One possibility is the channel was taken down over copyright issues considering the videos all originated from Apple. However, it is still possible that the owner received external complaints about copyright violations and proactively removed content from the channel.
