Consumer-generated advertising is a relatively new and controversial development, and it has created a new model of marketing communication from businesses to consumers. Among the various forms of advertising on blog, the most controversial are the sponsored posts. These are blog entries or posts and may be in the form of feedback, reviews, opinion, videos, etc. and usually contain a link back to the desired site using a keyword or several keywords. Blogs have led to some disintermediation and a breakdown of the traditional advertising model, where companies can skip over the advertising agencies (previously the only interface with the customer) and contact the customers directly via social media websites. On the other hand, new companies specialised in blog advertising have been established to take advantage of this new development as well. However, there are many people who look negatively on this new development. Some believe that any form of commercial activity on blogs will destroy the blogosphere's credibility. Legal and social consequences Blogging can result in a range of legal liabilities and other unforeseen consequences. Defamation or liability Several cases have been brought before the national courts against bloggers concerning issues of defamation or liability. U.S. payouts related to blogging totalled $17.4 million by 2009; in some cases these have been covered by umbrella insurance. The courts have returned with mixed verdicts. Internet Service Providers (ISPs), in general, are immune from liability for information that originates with third parties (U.S. Communications Decency Act and the EU Directive 2000/31/EC). In Doe v. Cahill, the Delaware Supreme Court held that stringent standards had to be met to unmask the anonymous bloggers and also took the unusual step of dismissing the libel case itself (as unfounded under American libel law) rather than referring it back to the trial court for reconsideration. In a bizarre twist, the Cahills were able to obtain the identity of John Doe, who turned out to be the person they suspected: the town's mayor, Councilman Cahill's political rival. The Cahills amended their original complaint, and the mayor settled the case rather than going to trial. In January 2007, two prominent Malaysian political bloggers, Jeff Ooi and Ahirudin Attan, were sued by a pro-government newspaper, The New Straits Times Press (Malaysia) Berhad, Kalimullah bin Masheerul Hassan, Hishamuddin bin Aun and Brenden John a/l John Pereira over alleged defamation. The plaintiff was supported by the Malaysian government. Following the suit,
