Experts say advertising offers you the right to choose Can you throw more light on "right to choose"

I am asking these questions for the purpose of enriching discussion on public relations cos going through the internet I discovered that public relations is probabaly one of the least discussed topics. Why? I actually have answers to most of these questions though not all and I think we got to find a way of getting people to put more papers, articles, documetary on the internet. As a matter of fact I do like to open a website/blog (in future) that we help people with public relations works.
