How technology is influencing economic diversity

• Researchers have conducted a multi-year project analysing global trends in online diversity and dominance.
• It analysed 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.
We conducted a multi-year research project analysing global trends in online diversity and dominance. Our research, published today in Public Library of Science, is the first to reveal some long-term trends in how businesses compete in the age of the web.
We saw a dramatic consolidation of attention towards a shrinking (but increasingly dominant) group of online organisations. So, while there is still growth in the functions, features and applications offered on the web, the number of entities providing these functions is shrinking.
Web diversity nosedives
We analysed more than six billion user comments from the social media website Reddit dating back to 2006, as well as 11.8 billion Twitter posts from as far back as 2011. In total, our research used a massive 5.6Tb trove of data from more than a decade of global activity.
This dataset was more than four times the size of the original data from the Hubble Space Telescope, which helped Brian Schmidt and colleagues do their Nobel-prize winning work in 1998 to prove the universe’s expansion is accelerating.
With the Reddit posts, we analysed all the links to other sites and online services — more than one billion in total — to understand the dynamics of link growth, dominance and diversity through the decade.
We used a measure of link “uniqueness”. On this scale, 1 represents maximum diversity (all links have their own domain) and 0 is minimum diversity (all links are on one domain, such as “youtube.com”).
A decade ago, there was a much greater variety of domains within links posted by users of Reddit, with more than 20 different domains for every 100 random links users posted. Now there are only about five different domains for every 100 links posted.
In fact, between 60—70% of all attention on key social media platforms is focused towards just ten popular domains.
Beyond social media platforms, we also studied linkage patterns across the web, looking at almost 20 billion links over three years. These results reinforced the “rich are getting richer” online.
The authority, influence and visibility of the top 1,000 global websites (as measured by network centrality or PageRank) is growing every month, at the expense of all other sites.
App diversity is on the rise
The web started as a source of innovation, new ideas and inspiration — a technology that opened up the playing field. It’s now also becoming a medium that actually stifles competition and promotes monopolies and the dominance of a few players.
Our findings resolve a long-running paradox about the nature of the web: does it help grow businesses, jobs and investment? Or does it make it harder to get ahead by letting anyone and everyone join the game? The answer, it turns out, is it does both.
While the diversity of sources is in decline, there is a countervailing force of continually increasing functionality with new services, products and applications — such as music streaming services (Spotify), file sharing programs (Dropbox) and messaging platforms (Messenger, Whatsapp and Snapchat).
Another major finding was the dramatic increase in the “infant mortality” rate of websites — with the big kids on the block guarding their turf more staunchly than ever.
We examined new domains that were continually referenced or linked-to in social media after their first appearance. We found that while almost 40% of the domains created 2006 were active five years on, only a little more than 3% of those created in 2015 remain active today.
The dynamics of online competition are becoming clearer and clearer. And the loss of diversity is concerning. Unlike the natural world, there are no sanctuaries; competition is part of both nature and business.
Our study has profound implications for business leaders, investors and governments everywhere. It shows the network effects of the web don’t just apply to online businesses. They have permeated the entire economy and are rewriting many previously accepted rules of economics.
For example, the idea that businesses can maintain a competitive advantage based on where they are physically located is increasingly tenuous. Meanwhile, there’s new opportunities for companies to set up shop from anywhere in the world and serve a global customer base that’s both mainstream and niche.
The best way to encourage diversity is to have more global online businesses focused on providing diverse services, by addressing consumers’ increasingly niche needs.
In Australia, we’re starting to see this through homegrown companies such as Canva, SafetyCulture and iWonder. Hopefully many more will appear in the decade ahead.

New research shows that the variety of online players is shrinking rapidly, although the overall size of the worldwide web continues to expand and functional and geographic opportunities are rising.
The Online Diversity Study published by Public Library of Science addresses an apparent paradox: the web is a source of continual innovation, and yet it appears increasingly dominated by a small number of dominant players.
This research tackles this paradox by using large-scale longitudinal data sets from social media to measure the distribution of attention across the whole online economy over more than a decade from 2006 until 2017. Here, we use outbound weblinks towards distinguishable web domains as a proxy for the market for online attention. As this data collection captures longitudinal trends relating to a universe of all potential websites and services, it serves as a valuable index of broader economic trends, dynamics, and patterns emerging online.
In this work, we provided evidence consistent with a link between increasing online attention on social media and the emergence (and growing) dominance of a small number of players.

The development of the web has been steady, and it came in functional waves, each of which has been predicated by the emergence of foundation platform technologies— such as secure encryption, enabling e-commerce; ubiquitous broadband, enabling the emergence of streaming video and mobility, enabling the emergence of many new functions including car sharing. This research outlines that while new functions, services, and business models continuously emerge online, the web dynamics are such that in many mature categories of online services, one or a small number of competitors dominate. Yet, as new web technologies continue to be developed, this enables more unexplored functional niches to emerge and for the cycle to repeat. Over time, this process leads to long-term declines in the overall competition, diversity, and decreasing survival rates for new entrants.
The world’s largest companies are now those that run global online platforms: Apple, Facebook, Google, and Amazon in the west and their counterparts Alibaba, Baidu, and Tencent in China. There is a growing public interest in the nature and extent of dominance on the web and web giants’ influence on economics, popular culture, and even politics.
This paper extends understanding of the nature and scope of the web’s network effects on the evolution of businesses today. This work also opens the door to further research that uses digital footprints of organisations en masse as a basis for analysis of the behavioural economics and competitive dynamics of markets online. There is room here too for further work in simulation extending previous work done in synthetic market experimentation and prediction.

Innovative global products and services, such as TikTok, Klarna and SkyScanner, continue to emerge from a range of creators around the world.
