Whenever a company finds a new and successful way to reach a goal, or to reach a hard-to-get-to audience - many others follow quickly - copycatting the original company, often times with dismal results. In some cases, as is the case with word-of-mouth marketing, new entrants screw up the whole playing field for everyone.
There are three main reasons why copycatting does not always work. First off, many companies who copy others do so without really understanding what the real ingredients for success are. The second reason, which took down email marketing and potentially could take down word of mouth marketing for all of us is related to ethics and industry self-regulation in the absence of government guidelines. And the third one is that best practices are not always portable from one company to another.
