Did the smackdown introduction om 99 pretty disturbs raw is war on Monday nights?
Did the Smackdown introduction on Thursday pretty much disturb Monday night raw especially during the attitude era? As i can see, the rating on raw pretty drops a little when smackdown was introduced.idk. but what was the reasons that cause the raw rating to drop since smackdown was introduced? your opinions?
