#4 Extending Raw to 3 Hours

Watch any of WWE's retrospective documentaries on the rise and fall of WCW and the same common criticisms are likely to be heard. Ironically, modern-day WWE often replicates many of those previous missteps with one of the bigger standouts being Raw's move from two hours to three.
Of course, there was an immediate financial benefit from the USA Network to provide an additional hour of content, but in doing so, WWE left themselves vulnerable to more long-term problems.
Not the least of which was taking an already saturated product (i.e., 6+ hours of weekly television content) and over-saturating it. This came in the middle of WWE's plan to add even more content via its own streaming service, the WWE Network. It should have come as no surprise that, soon after Raw expanded to three hours, the product suffered and RAW's hourly ratings would soon reach pre-Attitude Era lows.
