The Altering of Product Names

I came across this article at a website called The Media Awareness Network.  It says:

"Digital advertising goes one step further than product placement by using computer technology to add products to scenes that were never there to begin with. This practice is common in sporting events coverage, where ads are digitally inserted onto the billboards, sideboards and playing surfaces in arenas and stadiums.
While digital ads are mainly used in sports coverage, virtual advertising is starting to break into the entertainment world as producers digitally insert products into TV scenes after the scenes are shot. The technology also allows product names to be altered in scenes, creating the potential for new advertising revenues when series are sold into syndication."

I find the altering of product names to be really interesting and look forward to what technology has in store for us in the future.
