Not to mention that more and more this javascript is spent calculating whether an ad is being viewed are not and phoning that data back home. Ad providers do this in different ways and it's not uncommon to see them send down a full jQuery build with their ad.
- manigandham 11y agoYes, I mentioned all this in the other paragraphs. Ad networks have a lot of work put into the backend systems but the frontend stuff that runs in the browser has been ignored for a long time. Even Google still uses things like Document.Write for putting more tags on the page, something that was obsolete about 6 years ago.
