Las Vegas has opened a new entertainment venue called the Sphere, which is the world's largest spherical structure. The Sphere features a stage and a high-resolution LED screen on the interior, offering a unique immersive experience for visitors. The venue can accommodate around 18,600 concert-goers and offers exceptional visuals on a massive screen. The first performers at the Sphere were the band U2, who are scheduled to play 25 shows at the venue. Companies wishing to advertise on the Sphere's screens will have to pay a substantial fee.
