Nathan Mattise wrote about ISS, a company that makes fake products:

• When movies need prop-products in their scenes ISS creates the fake brand and packaging.
• The need for this is not as great as it once was. In the era of cross-promotion movie producers prefer to just use real products – and charge the brand a fee for the advertizing.
• However if a product or item is to be portrayed in a negative way then the owners of the brand might not be happy with its use. This is when fake products come in.
• Products and audiences’ expectations of products are constantly shifting. To keep up the veneer of realism ISS continuously monitors the latest developments and advancements in various fields.
