The fact that it is so widely used should tell you that it is effective.

Here is a small primer on the psychology of slogans: http://www.adslogans.co.uk/ww/prvwis11.html

Did you really link to material on an ad company's website in order to provide evidence that advertisements are effective? Would you expect anything other than "ads are useful and effective" from an ad company?

More importantly when OP said the slogans were annoying/disgusting, it was a statement of OP's personal opinion. OP never said in general the public finds these slogans disgusting/annoying.

An ad hominem if I have ever seen one! To answer your question though, yes as it gives a simple, researched and concise explanation as to why these are useful and might make the commenter think that they aren't as "meaningless" as they seem.

I am not sure why you interpreted my comment as an ad hominem but I sincerely apologize for offending you, that was not my intention.
