In America, the media holds a powerful and effective position in politicizing and socializing the general populace. The main political function of the media is to inform and analyze while being accountable. However the question of whether the media produces a pluralist democracy, or fosters a "one dimensional society" still remains unanswered. Many contemporary philosophers conclude that the media does contribute to both, some even postulate other drawbacks, for instance they posit that the media maintains elite power both in the corporate and political sector. On the other hand, some intellectual thinkers have theorized that the media, especially advertisement, is a major influence to substantiate the economy.
One common belief shared by all contemporary media critics is that the media reflects and produces values of its own, even though their onus is initially to inform. In America the media has become a corporation in a corporate dominated society, it has become a bias agency of politicization. Powerful business corporations and politicians intertwine, both using the media to indoctrinate the mass populace in order to consummate a political and social consensus. This in turn maintains their elite positions. "Hollywoodism" and advertisement contributes to American imperialism by generating a desire among oversea consumers to buy American products. The impact of the American media has politicized a pluralist democracy among the majority by creating a marginilized society, leaving the corporations, including the media, and the American politicians at the top of the pinnacle concerning political decisions and elite power.
Mass communications used to be, in itself, an autonomous solely owned corporation. However, this changed by the 1980's, the majority of all major American media- magazines, televisions, radios, books, newspapers, and movies- were controlled by fifty giant corporations.
