有人认为，大媒体公司和新闻编辑室里的大多数记者在个人政治上都有左倾倾向和保守主义倾向。这导致他们在诸如堕胎、同性恋权利、平权行动、枪支管制等问题上有偏见，他们倾向于认为他们的方法是合理的，在道德上是正确的，从而导致了他们所传达的新闻偏见。这种媒体集中的模式不仅在美国和澳大利亚，而且在世界上的许多其他地方，如英国、加拿大和欧洲(Ngai et al .，2015)都有。例如，澳大利亚出生的美国人Keith Rupert Murdoch在上世纪50年代和60年代在澳大利亚和新西兰收购了许多报纸，然后在1969年在英国扩张。默多克的“媒体帝国”是巨大的，包括澳大利亚和美国的出版社，节日记录和20世纪福克斯(Kellner,2012)。它有能力制造和打破新闻、政治家和报纸。众所周知，它经常反对和平运动、进步的社会计划和工会，滥用权力。它还承担了对社会的负面影响，以支持死刑、降低税收政策和采取强硬的外交政策(Freedman,1996)。
It has been argued that the majority of journalists in big media houses and newsrooms have a leftward bent and conservatism in their personal politics. This leads to their biased approach on issues like abortion, gay rights, affirmative actions, gun control etc. They tend to assume that their approach is reasonable and morally correct, leading to bias in the news communicated by them. This pattern of media concentration is not only found in the US and Australia but many other parts of the world such as Britain, Canada and Europe (Ngai et al., 2015). For example, Australian born American Keith Rupert Murdoch acquired many newspapers in Australia and New Zealand in 1950s and 1960s before expanding in the UK in 1969. Murdoch’s “media empire” is huge which includes publishing houses in Australia and the US, festival records and the 20th Century Fox (Kellner, 2012). It has the power to make and break news, politicians and newspapers. It is known to have misused its power by constantly opposing peace movements, progressive social programs and trade unions. It has also been responsible for a negative impact on society by supporting death penalty, lower tax policy and hawkish foreign policies at any cost (Freedman, 1996).
