By the technological convergence of media, IT and telecommunication, weblogs are generated as a new phenomenon of communication. More and more companies include weblogs strategically into their marketing mix for specific corporate and brand communications. In the USA there are already more than 5.000 corporate blogs, in Germany more than 300.
The Top-10 corporate blogs are ranked by different institutions with varying criteria. The following Top-10-list arranged (by technorati in May 2008) two main criteria: popularity (number of blogs linking to a website in the last 6 months, the higher the number, the more authority the blog has) and the number of blogs vs. number of links that’s being measured.
