Tech Crunch - Over one-third of web pages published after the release of ChatGPT show signs of being written by AI, according to a new study from Pew Research released on Thursday. The report corroborates other studies that detail how much of the web’s newer web pages are now either written by or “substantially edited” by AI, the firm says.

….To compile the report, Pew said it used the Common Crawl web archive to collect nearly half a million English-language web pages from the past five or so years, starting a couple of years before ChatGPT’s November 2022 release. Pew then used Open Pangram’s technology to detect how many were likely written or heavily edited by AI.

In a random sample of 10,000 web pages collected in July 2026, around 10% showed “significant signs of AI authorship,” Pew said. However, Pew pointed out that a random sample like this would inevitably include older web pages — ones published before AI writing tools even existed, and therefore couldn’t have been AI written.

Pew Research -  Today, 52% of Americans say they are more concerned than excited about the increased use of AI in daily life – up from 37% in 2021. Another 9% are more excited than concerned and 37% say they’re equally excited and concerned, according to a Pew Research Center survey conducted June 22-28, 2026.  Concern about AI is up among younger and older Americans alike since we first asked this question in 2021. But while the rise was mainly in the first two years for Americans ages 30 and older, concern continues to climb for adults under 30 – whose skepticism of AI has made headlines in recent months.
