Poll reveals TV news too negative
A recent Time/CNN poll in the USA has discovered that 75% of people agreed that the news media is "sensationalist",63% found it "too negative" and 73% said they are "sceptical about the accuracy" of the news they are receiving.
Local news programmes in the USA are so dominated by stories of violence and crime that other topics like government,education and the environment are left with little airtime.1 Network broadcaster John Walters claimed,“This lack of information has resulted in negative feelings towards the media.”
Crime reports,which often serve as lead stories,make up an average of 30.2% of news time on local TV news programmes in the USA.Media researcher Bob Smith reported,“53% of crime reports are about murder,but it is one of the least frequently committed crimes.” Another media study revealed that 42% of all local TV news broadcasts are stories about crime,disaster and war.
One possible reason for this is that local television news is ratings driven2.Some market research suggests that viewers like to see stories of crime and violence,which increases the ratings of newscasts.Higher ratings mean higher advertising revenues.Mike Adams,a television executive,explained,"The increase in crime reports is because,on average3,almost half the money a local station makes comes from news."
Many experts believe a steady diet of violence-oriented news broadcasts has serious effects.A spokesman for the National Television Violence Committee stated,“There are three main risks associated with viewing media violence.People learn aggressive behaviour.They become desensitised to real-world violence.These lead to an increased fear of being a victim of violence,resulting in mistrust of others.”

调查显示电视新闻过于消极
时代杂志/美国有线电视新闻网最近在美国进行的一次调查表明,75%的人认同新闻媒体是哗众取宠,63%的人觉得新闻过于消极,有73%的人说他们对所接受新闻得正确性持怀疑态度.
美国地方的新闻节目暴力犯罪故事过于泛滥,以至于诸如政府、教育和环境等方面的话题几乎无暇可播.一位网络播音主持约翰.沃尔特斯(John Walters)声称：“这种信息的缺失已经对媒体产生了负面的影响”.
在美国,常作为头条新闻的犯罪报道,平均要占据当地电视新闻节目30.2%的新闻时间.媒体研究员鲍勃.斯密斯(Bob Smith)报导说：“有53%的犯罪报道是关于谋杀的,然而谋杀却是最少发生的一种犯罪”.另外一项媒体研究显示,42%的所有地方电视新闻节目充斥着关于犯罪,灾难和战争的故事.
造成这种情况的一个可能的原因就是,地方电视新闻节目为收视率所驱使.一些市场研究表明,观众喜欢看犯罪及暴力的节目,这会提高新闻广播的收视率.而高的收视率意味着较高的广告收益.迈克.亚当斯,一位电视台主管,“犯罪报道的增加,大体上是因为几乎地方电台一半的创收来自于新闻”.
很多专家认为,持续的以暴力为导向的新闻广播会产生严重的影响.国家电视暴力委员会的一位发言人称：“对于媒体暴力会涉及到三个主要的风险.人们会学习攻击性的行为.他们会对现实生活总的暴力变得熟视无睹.暴力报道会导致观众特别害怕成为暴力受害人,并造成对他人的不信任”.
