I'm not seeing his definition, what is it?
looking it up, wiki defines it as
"
Streaming media is
multimedia that is delivered and consumed in a continuous manner from a source, with little or no intermediate storage in network elements.
Streaming refers to the delivery method of content, rather than the content itself."

that definition fits my understanding -- is it aligned with yours?
I'm not following how your comments about ESPN are relevant to the topic of "what is streaming?" What's the signficance of whether the parent company has a different business unit for linear programming and one for streaming? if you're getting ESPN content on your phone, I think that's 'streaming' by most any conventional understanding. I'm probably missing something fundamental here.
