What is it about?
New research analyses a massive amount of data from across the entire web including over a decade of data from global social media platforms to show that the variety of online economic players is in longtime decline, although the overall size of the worldwide web continues to expand and functional and geographic opportunities continue to grow.

Why is it important?
This work explores the dynamics of competition in an online world at a massive scale and over a decade. Researchers conducted a multi-year research project revealing global trends in online diversity and dominance. It examined more than six billion user comments from Reddit, as well as 11.8 billion posts from Twitter. The results show a dramatic consolidation of attention towards a shrinking (but increasingly dominant) group of online organisations. The online world is continuously expanding — always aggregating more services, more users and more activity. Last year, the number of websites registered on the “.com” domain surpassed 150,000,000. However, more than a quarter of a century since its first commercial use, the growth of the online world is now slowing down in some key categories.

Tracking the decline in global economic diversity
Dynamics of activity on online platforms, as indicated via posts in social media platforms. (A) Growth in the number of posts (dotted) and links within posts (solid) in both Reddit and Twitter over time. (B) The number of distinct active domains appearing within social-media links to has also grown. (C-D) An increase the HHI index (C) and a decrease in link originality (D) for domains within links indicates that, despite the growth in total activity (A-B) diversity in online activity is in long term decline (see Sec. Materials and methods).
