This past weekend, thousands of sports fans flocked to the Jacob Javits Convention Center in New York to experience the first immersive and interactive sporting event of its kind, and most of them brought their little ones with them. Parents brought their children, uncles and aunts brought their nieces and nephews, because it was announced that there would be activities for the kids. What was not announced was that hip-hop stars from every generation would be chatting with the sports legends at this monumental event.

The three-day festival kicked off Friday with exhibits for fans of all sports, including a full UFC ring near the entrance. Hundreds of booths selling and trading sports memorabilia, such as a $5,500 box of Wheaties signed by Michael Jordan or a $300,000 baseball signed by Hall of Fame legends Babe Ruth and Ty Cobb. If you’re a young autograph hunter looking to snag a few legendary signatures, HOFers from all sports such as Giants legend Lawrence Taylor, the Mets’ 1986 World Series champions Dwight Gooden and Dwight Strawberry, NBA stars Jalen Rose, Kevin Durant, Jalen Brunson, Walt Frazier, Julius “Dr. J” Irving, wrestling legend Hulk Hogan and even controversial sportscaster Stephen A. Smith were in attendance.

At Fanatics Fest, literally millions of sports and trading cards (Pokemon, Garbage Pail Kids, etc.) were bought, traded, sold and given away. For those interested in engaging conversations surrounding sports culture, there were also panel discussions titled “Courtside Conversations” and “The Ultimate Fantasy Draft,” while several live podcasts ran across radio and the internet.

There were too many live sports activities to list, from the MLB’s simulated Playball Park, where kids got a chance to hit a few home runs, to the NBA hoops that seemed to be filled to capacity all weekend long. Soccer and hockey goals, boxing/punching bag challenges, mini football fields, wrestling rings, and everything in between filled the main floor of the Javits Center. Kids were the primary participants in these activities, but their parents and guardians seemed to be focused on something other than just the sports fanatics’ imagination.

On any given day, music could be heard throughout the convention center, but the front of the temporary club, dubbed the “40/40 Club,” was only visible through a back entrance accessible only to press and celebrities. Those who really wanted to see what all the camera flashing was about waited on the side near the food court to catch a glimpse of the celebs making their way to the red carpet. The kids saw some of their favorite personalities stop by the 40/40 Club, the exclusive sports bar/nightclub Jay-Z founded in Midtown Manhattan in the early 2000s. This activation at the Javits Center was created in partnership with Fanatics Sportsbook, which created the entire event. Quavo of The Migos and Lil Baby were spotted entering the invite-only club, while Travis Scott was even seen signing a pair of his own Nike Travis Scott sneakers for a young fan before dropping into the scene. That’s what Fanatics Fest is all about.

The OGs got to see some of their favorites, including Fat Joe, DJ Khaled, comedian Michael Blackson, and more. Most notable, of course, was Jay-Z’s personal appearance at the club built in his honor, which caused so much of a stir that fans on the other side of the entrance tried to sneak a photo of Hov, whose sighting fueled rumors that he was opening a new 40/40 club and casino.

With just as many hip-hop stars making cameo appearances at this exclusive sporting event, it’s guaranteed that many attendees will be looking for their favorite rapper rather than their favorite ballplayer next year. FanaticsFest was a successful example that sports and music culture are not far apart and that when it comes to entertainment, you can only give people who and what they want.
