I think we can expect even broader news coverage after the hearing is over. Right now everything is regarded as "allegations". It is now that the evidence is being presented. Any rational news outlet will limit itself to report that the hearing is ongoing at this stage. If anything meaningful comes out of this hearing, I am pretty sure it will receive wider exposure.
I doubt the US will see a hearing like this one any time soon, we are just too conservative to admit our faults. I think it will happen eventually but judging on past history, it will have to involve an abuse case taken all the way to the supreme court for anything these significant to happen.
