From VOA Learning English, this is IN THE NEWS in Special English.
This Sunday, people around the world will witness two teams as they battle for the championship of American professional football. The Baltimore Ravens and the San Francisco 49ers are in New Orleans, Louisiana, to prepare for the 47th Super Bowl. Over one hundred million people are expected to watch the game on television, with computers or other devices.
The Ravens were formed in 1996 when the owner of the Cleveland Browns decided to move his team to Baltimore, Maryland. In 2001, the Ravens won their only Super Bowl game. The 49ers were established in 1946 as a member of the All-American Football conference. The team joined the National Football League in 1950.

They have won five Super Bowl championships.
VOA reporter Jim Stevenson will be going to the game on Sunday.
"This is a really good match up. Most people thought that the 49ers were one of the favorites to reach the super bowl. They have an exceptional defense, explosive offense. Baltimore has always been known for its defense, very tough, physical, hard hitting team."
This Super Bowl game is unusual because the head coaches of the two teams are brothers. Baltimore's John Harbaugh is the older of the two. Younger brother Jim formerly played for several professional teams, including the Ravens. He was a college football coach before moving to the NFL last year to lead the 49ers.
The Super Bowl is not only a popular event to watch, but it also increases economic activity in the United States. Many people hold Super Bowl parties, spending lots of money on food, drinks and activities. Officials estimate the game will bring $434 million to the Louisiana economy and increase the number of visitors to the state.
A major part of the economic activity is coming from large companies that plan to advertise their products on television during ‘commercial' breaks. Companies are spending up to $400 million for a single 30 second advertisement. But businesses would not spend this much money if they did not think it would lead to increased sales. The head of Volkswagen America told the Reuters news agency that the company's recent Super Bowl ads have resulted in a doubling in the size of its business.
This year, companies are recognizing the importance of social media. They know that many people will not only be watching the television broadcast, but will be near their computer or mobile phone. Coca Cola wants people to take part in its advertising. On Sunday, the company will be asking viewers to vote in an online competition between three groups competing for a Coke. Pepsi and Toyota are planning to use personal photographs in their ads.
In the past, Super Bowl ads were closely-guarded secrets. But over the past few years, more and more companies have been making their ads public before the game. This year more than 20 companies have already released their ads. However, not everyone enjoys seeing the ads early. Some people like to be surprised. Because advertising during the Super Bowl is just as competitive as the game itself, some companies could change their ads at the very last minute.

本周日，全世界的人们将观看两个球队争夺美国职业足球锦标赛比赛，巴尔的摩乌鸦队和旧金山49人队正在路易斯安那新奥尔良准备开始第47届超级碗比赛 。将有100万人通过电视、电脑或其他设备来观看 。
1996年，克里夫兰布朗队的老板决定将球队搬到马里兰州的巴尔的摩，乌鸦队由此产生 。2001年，乌鸦队赢得唯一一次的超级碗决赛 。49人队成立于1946年，是全美橄榄球联合会的一员，1950年，该队加入了美国国家橄榄球联盟（简称NFL） 。
“这场比赛势均力敌，大多数人都认为49人队是超级碗的热门球队之一，他们的防守都很棒 。巴尔的摩也因防守著称，这是一个很非常顽强、体质很好、势不可挡的球队 。”
这次超级碗比赛非同寻常，是因为两个球队的主教练是兄弟两 。巴尔的摩的约翰·哈博是哥哥，弟弟吉姆曾为包括乌鸦队在内的几个职业球队工作过 。去年他来到NFL率领49人队，此前曾是大学足球教练 。
超级碗不仅是一场热门比赛，还促进了美国经济活动的发展 。许多人举办超级碗聚会，在食物、饮料和各种活动上花了很多钱 。官方估计这场比赛将给路易斯安那的经济带来4.34亿美元的收入，还使大量游客前来参观 。
经济活动的一大方面来自大公司，他们计划在比赛休息期间在电视上为产品打广告 。一段30秒的广告就要花4亿美元，但如果公司认为广告不会促进销售，也就不会花这笔钱 。大众美国公司负责人对路透社说，大众最近在超级碗的广告使公司的销售增加了一倍 。
今年，各公司都意识到社交媒体的重要性 。它们知道很多人不仅看电视直播，还会通过电脑或手机观看 。可口可乐希望人们加入到广告中来，周日，该公司将邀请观众在三人组竞争一罐可乐的比赛中投票 。百事和丰田将在广告中使用个人照片 。
以前，超级碗广告很保密 。但过去几年来，越来越多的公司开始在比赛之前投放广告 。今年，20多家公司已经发布了广告 。然而，不是每个人都希望早点看这些广告 。有的人希望看到惊喜，因为超级碗期间的广告像比赛一样竞争激烈，有的公司可以在最后时刻改变广告 。
