WWE officially kicked off WrestleMania 40 by unveiling a new video introduction. WWE programming has been using the "Then. Now. Forever. Together" slogan to welcome viewers to live television events and premium live events (PLE), with footage spliced featuring superstars throughout WWE history. Icons such as Hulk Hogan, The Rock, Stone Cold Steve Austin, Undertaker, John Cena and more have been included on these WWE intros, and with this year's WrestleMania marking the 40th event, it looks like it's time for another new take on the intro. It's only 30 seconds long, but it uses its time wisely and helps set the stage for WrestleMania XL.
