I would be interested to see that article. I tried googling for it but could only find some articles about censorship on Chinese streaming sites and Netflix missing some scenes from the DVD release due to issues with the master copies.
There was a case of it just recently—the Amazon Jack Reacher series was released in February (around tax time) and had a TurboTax ad edited onto the side of a building when viewed in America.
It was probably 10ish years ago I read about it. Most likely on BoingBoing.
Will see if I can find it. Indeed it is not easily dug up.
There are many ads about the coming trend of "Virtual Product Placement" but none that I can find which acknowledge the early attempts at it which I read about way back.
I read an article a while back about how old Friends episodes have movie posters in the background of films which were released after 2010.
