Sun Microsystems’ Pioneering Co-Founder Gives A Rare Interview

Basically it goes like this, attack your competitors, wind them up in the press as a form of advertising. This creates enormous attention for nothing (people actually read editorial and skip the ads) and often you need an adversary to make something newsworthy.

Be ethical but let the industry know there is battle on and you're fighting for your life, but fight on safe ground!

This is the method I personally used with some success in my former business which was also an electronic hardware, design and manufacturing company. With very little funds for marketing I had to be creative, we made impressive DPS adverts and coupled these with side stories which were often gossip over industry turf wars or other antics I would get up too.
