So you know why all those viral sites are so slow? It is because they utilize a technique that queries the ad server first in the header of the page, then figures out what ads to serve. AFTER ALL THAT then it decides to load the rest of the page.
One reason people state to defer javascript to the end of the page aka remove it from the header is so the page loads faster. So in essence loading javascript in the header does the exact opposite of speeding up the site. And you always notice the advertisements load first right? Of course cause they've got first priority cause they've already got the logic behind them while rest of the page has been sitting around waiting.
Here is the thing, Google's always had the technology to go around this and they utilize it only for themselves. But since the demand is so great and publishers are looking for a way to bid, Google now realizes if they want a faster internet they'll have to give up the advantage they've held for years and open that sucker up:
Sauce: Header bidding was the latest trend in ad tech designed to take on Google — now Google has effectively stamped it out
What this means for average visitors is faster loading on those viral sites. Yay?

In addition, Google also announced on Wednesday that all of its DFP clients will now be able to use a new product called "First Look," which allows publishers to give all of its programmatic ad buyers the chance to bid on 100% of their inventory, including ahead of sponsorships and reservations. The product had previously only been available to a test group of publishers.
