I'm quite happy to believe the trend, at least. Do you have a preferred assessment or even a rebuttal (back of the envelope, whatever) for around that time? BT for media is a real sweet spot. Music particularly because people _collect_, though I don't know what the timeline would look like for music v.s. video. Not as if the original figure was being cited as scientific gospel. The last paper out of Netflix, they said it works best to stomp out the isochronous behaviour and run in FTP mode as much as possible :). (Subject to upper limits on quality and application buffers). Even dumb chunk downloading uses TCP; it's not isochronous in the way that's usually used to describe RTP etc.
