WrestleMania, explained

Still, WrestleMania is about far more than carnage. As WWE’s seminal showcase, it offers the pomp and circumstance of the Super Bowl crossed with the Rose Bowl Parade. Every year WrestleMania gets bigger — and longer — with a week’s worth of events leading up to Sunday’s five-hour main show, all broadcast live on the WWE Network. WrestleMania is also uncommon as a narrative platform, functioning both as a season finale for a year’s worth of WWE storylines and a springboard for the future.

If you’re not a wrestling fan, you probably know WrestleMania exists but associate it with the past and names like Hulk Hogan, who helped the event reach mainstream popularity in the 1980s. Yet despite a few brief lulls, WrestleMania’s popularity never truly waned; now it’s arguably bigger and more profitable than ever.
