I found an interesting website which is full of facts about social media. Statistics are from the last year.(http://www.onlinemarketing-trends.com/2010/11/social-media-in-2010-top-10-social.html ) So what has social media done to the traditional advertising, such as TV and newspapers? I found out that only 18% of TV campaigns generate a positive return of investment. What comes to newspapers, they have lots of problems. 24 out of the 25 largest newspapers are experiencing declines in circulations because the news reach users in other formats. For a marketer these numbers are critical, you really need to think about how to reach your customers because of social media.
Word of mouth is more powerful than other advertising formats. The fact is that only 14% trust advertisements, but in terms of impact of social networks on advertising, word of mouth is the most popular option with 78% of customers trusting peer recommendations on sites. What would be better for a brand than everyone speaking of it or recommending the brand.
There are people like Rebecca Black who´s video has been watched very many times. But there can also be a commercial which gets a lot of viewers. One example is commercial from Samsung. (http://www.youtube.com/watch?v=D2FX9rviEhw) Extreme Sheep LED Art. It´s a few years old, but when it came in 2009, a year later from that, the video had been watched more than 11 000 000 times. Today, more than 14 000 000.
There can also be questionable ways to try viral marketing. For example in 2009 Denmark's official tourism agency had a viral marketing campaign, but a hoax one. There was a model pretending to be a desperate new mother who had a one-night stand. In the end, the revelation caused an outrage in the country and the video was removed. When the commercial came, in five days, more than 800 000 had seen the commercial and later the amount increased over one million. Well, this is all about ethics. But I think it crossed a line.
