Pop Up Affiliate Ads – A new way of earnings?

Hi,

I am writing this to inform you what I experienced personally. I believe there are people who uses pop up advertisers to show their affiliate ads in sites. Is this something new in the market or it has been for a very long time.

example:
www.amazon.com/affl-id=2144
www.flipkart.com/affl-id=312123

These are just examples of the pop up ads looks like in new tab.

Thanks.
