What I want to know is what is the difference between spam and advertising? If we can now say, "You can't send me spam", can we not also say "you can't send me advertising"? If spam is an invasion of privacy, then isn't a billboard on the side of the street also an invasion? What about the flyers that appear in your mailbox and on your doorstop? Isn't that spam too? Why do we have radios in all our cars? So we can pipe advertising into a captive audience. Why do we have televisions in all our homes? So we can pipe advertising into a captive audience. Why do we have our computers plugged into the internet? Do we really need advertising?
