Here’s How Oversized Web Ads Are Encouraging Ad Blocking – WSJ
Some publishers say that ad agencies are as much to blame for the rise of ad blocking because they consistently send oversized digital ads, which cause Web pages to load slowly.
Here’s another reason more people may be blocking Web ads: The business of creating digital ads is bloated and slow.

This behavior is contributing to how slowly some Web pages are loading, encouraging the growing use of ad-blocking software among consumers, they argue.
