First came product placement. In exchange for a payment, whether in cash, supplies or services, a TV show or a film would prominently display a brand-name product.

Then there was virtual product placement. Products or logos would be inserted into a show during editing, thanks to computer-generated imagery.

Now, with the rise of Netflix and other streaming platforms, the practice of working brands into shows and films is likely to get more sophisticated. In the near future, according to marketing executives who have had discussions with streaming companies, the products that appear onscreen may depend on who is watching.

In other words, a viewer known to be a whiskey drinker could see a billboard for a liquor brand in the background of a scene, while a teetotaler watching the same scene might see a billboard for a fizzy water company.
