The US government typically doesn't try to preemptively regulate things (which is getting to be a problem as it now is too sclerotic to respond quickly to developments). Streaming services in 2010 were mostly paid subscriptions with no ads, I don't think the idea was on anyone's mind.
YouTube existed in 2010, and was primarily supported by ADs. Sure at the time it didn't really show what would traditionally be considered television, but it seems like the same logic would apply.
