Everything you should know about the Sphere: Las Vegas' multi-billion dollar entertainment venue

It started as a simple sketch - a circle with a stick person inside. Seven years later, that drawing has been made real: A $2.3 billion (€2.19 billion) massive spherical venue, standing 366 feet (111 metres) high and lighting up the Las Vegas skyline.

The drawing was initially made by James Dolan, the executive chair of Madison Square Garden and owner of the New York Knicks and Rangers. 

Together with David Dibble, CEO of MSG Ventures, they embarked on a mission to revolutionise the entertainment venue industry in Las Vegas.

Now Dolan and Dibble have recently unveiled their billion-dollar investment to the world, which has so far been viewed as a monumental success. 

“It really is a new medium,” said Dolan, speaking to the media during a walkthrough.

"When you’re in the Sphere, you don’t get told what to look at. The audience decides what they want to focus on.”

Inside the 516-foot-wide (157-metre-wide) Sphere, a high-resolution LED screen (the largest on earth!) wraps halfway around the 17,600-seat audience. 

Out of these 17,600 seats, 10,000 provide an immersive experience with a specialised sound system capable of making guests "feel" sound vibrations.

The Sphere proudly boasts having the world's largest concert-grade audio system, comprising 1,586 loudspeaker modules, 167,000 speaker drivers, amplifiers, and processing channels, as well as 300 mobile loudspeaker modules. 

Together, these components deliver a "crystal-clear" and multi-layered audio experience.

Not only is the interior of the building impressive, but its exterior also boasts 1.2 million hockey puck-sized LEDs that can be programmed to create dynamic and colossal image displays.
