Stadium screen, beautiful scenery of World Cup venues

FIFA said that fans going to Russia to watch the World Cup this year would not be confused because the video assistant referee (VAR) made a decision and the relevant game pictures would be replayed on the LED screen and provided with text explanations to inform the ball. Why did the fans make such a penalty? Why is it that such a piece of news attracts the attention of the fans and makes people feel relieved? This is tied up with those ugly, dirty foul Wars - the World Cup Stadium violence. in the 2010 World Cup in South Africa, Spain won the World Cup, but the game was flawed: in the final, Nigel DeJong of the Netherlands roughly kicked Spaniard Xavi Alonso in the chest with his soles, but he was not sent off by the referee on duty. However, it is not unreasonable to call the World Cup a "war" when South Africa is not even in the top ten, as in the 1938 World Cup in France, where three players left the field. The Swiss World Cup finals in 1954 also saw three players leave the field and a number of large-scale fights, known as the Bern Battle. The most famous was the 1982 World Cup semi-final when German goalkeeper Schumacher badly knocked down French footballer Patrick Batiston, causing the latter to be in shock on the spot, and the 2006 German World Cup final when French footballer Zidane headbutted Materazzi. Having said the dark history of the World Cup, we should also see the development of the World Cup in recent years. The World Cup is an area of extraordinarily strong external relevance, competitive sport is also a commercial activity, which contains great commercial potential and economic value. For China, the poor performance of the FIFA over the years does not stop the Chinese from loving football. As Hassan, Secretary-General of the World Cup Organizing Committee, said, China will be one of the countries with the largest number of football tournaments to Qatar in 2002. Their football market potential is enormous. Today, sports are commercialized. This is a fundamental advantage. With its growing popularity, the participation of the public is getting higher and higher, the design of the stadium is getting higher and higher, and the rules of the competition are becoming more and more standardized. Advertising costs for competitions have also risen, and as a medium of advertising, it has ushered in a new generation. From the limited collection of all kinds of information, we can know that in the early sports events, the courtside advertising method is relatively simple, basically text-based. A sponsor fixed a style of advertising, locking a billboard in a single form. If you need to change the advertising style, you need to re create billboards. Nevertheless, as the world's first sport football, still attract many sponsors, brand promotion in this form, for the football market commercial development has laid a certain foundation, after development, a new generation of advertising artifacts - LED display appeared!!!
