Great PR in Action

I can't remember seeing an ad. for Hewlitt Packard (HP) yet they are favoured by the general public. During a recent meeting with small-business owners, when the conversation turned to environmental impact, one gentleman actually used the brand name, saying "HP give paper envelopes with new ink cartridges, to return the old ones for recycling- free of charge."
Here is a classic example of great PR in action. By identifying a public trend (recycling) and backing a worth-while cause (saving the environment) HP have set themselves apart from the competition as leaders; by simply collecting their own garbage for free!
Of course the idea for this promotion would not have been free. I'm sure HP spent a pretty penny on PR services, but considering the results; it's obviously money well spent ;-)
