Introduction The financial tsunami is sweeping the globe, from the financial 代写ASSIGNMENT industry, real estate, retail to manufacturing, and Media is difficult to escape .A number of European and American media group announced the layoffs, restructuring, and both of newspaper sales and advertising volume shrinkage have been compounded the media situation even more so. This paper analyzes the problems of media on distribution, advertising and financing, thus from the SEO and paid distribution form online two aspects to explore how the media to deal with credit crisis. The Credit Crunch Impacts on the Media First of all, it is on the distribution.

(Adorno, T.W. 1975) However, with the economics point of view, the media product is not a necessity, but rather a optional item. With the economic crisis, national income is generally shrinking, and the demand for media products will decline naturally. (Hall, S. ed., 1978). Second, it is on the advertisements.

(Curran, J. & Seaton, J., 1997) In the end, it is on the financing. The U.S. financial tsunami resulted from the collapse of sub prime credit market, which caused the overall credit crisis. (Eysenck, H. and Nias, D.K.B, 1971) Perhaps the mere reduction in the amount of circulation and advertising is still not make a big media group in trouble, but when coupled with the stock market collapse which led to a drastic shrinkage of the market value and the credit crisis which resulted from the excessive borrowing, even the most well-known and most powerful media group probably could not escape.
