My take on the best collateral you can have: article reprints. It’s a great way to demonstrate that an independent, authorative source has written and covered your company. See below for a sample reprint from a story in EE Times in regards to our client, Discretix.
Most publishers sell or license the reprint rights to these articles and they are worth every penny. Printed versions can be handed out at tradeshows, presentations, and for your salesforce. Electronic versions can be put on the media coverage section of your web site.
