Jumbotrons or in-arena scoreboards make going to games that much more enjoyable because if you miss a play, you can always see it on the scoreboard and still enjoy the incredible atmosphere.
Plus, it's always fun to try and get on the jumbotron and do something funny, whether it be dancing or the dab.
In-arena scoreboards come in all shapes and sizes, but only one center-hung, in-arena scoreboard can be the largest in the world and it can be found in New Jersey at the Prudential Center.
On Friday, the Devils unveiled the scoreboard and this cool video gives you a behind the scenes look at how it was built.
The Devils also tweeted some fun facts about the new scoreboard that any hockey fan would enjoy.
The Devils and their fans will be able to enjoy the new scoreboard on Saturday when the team plays their first game of the season at home against the Avalanche.
