Map: Internet Censorship Around the World

Published

on

In January 2011, Egyptian activists, inspired by a successful uprising in Tunisia, began organizing a demonstration using Facebook. In a matter of days, thousands of protesters – who learned about the event through the social media platform – gathered in Cairo’s Tahrir Square to protest the longstanding Mubarak regime.

Then, in an attempt to quash civil unrest, the Egyptian government soon took the bold step of cutting off the country’s internet access. As the size of protests swelled from thousands to millions of people, the Mubarak regime quickly realized their mistake: never cut off a millennial’s internet access.

Mubarak was ultimately forced to resign after just 18 days of massive protests, but in that time Egypt’s Arab Spring demonstrated two major things: (1) the incredible organizing power of the internet, and (2) the how quickly a government could slam the door on the free flow of information.

The Egyptian government was able to quickly and effectively shut down the chokepoints that connect its citizens to the outside world. Etisalat, for example, is a centrally located routing system that could see up to 58% of Egypt’s IP addresses.

In other words, Mubarak was essentially able to blockade every website in the world by making a few simple phone calls.

A New Era Of Internet Censorship

Egypt’s dramatic internet shutdown became a new template for other precarious regimes, but also sparked a broader global conversation around online censorship.

Today’s infographic comes to us from WhoIsHostingThis and it provides a detailed look at varying levels of internet censorship around the world today.

Internet Censorship World Map

Internet users in North America and Europe enjoy relatively unfettered access to online content, while most countries in Asia, Africa, and the Middle East have some level of censorship. Torrenting is restricted in almost every country in the world, with a notable exception being Switzerland, where a laissez-faire approach is applied to downloading content for personal consumption.

It’s also worth noting that this map does not address government surveillance, which is ubiquitous even in countries with high levels of internet freedom.

The Anti-Information Age

If you want to liberate a country, give them the internet

–Wael Ghonim, Egyptian internet activist

Much of the world’s population accesses an internet that is at least partially censored. Countries have different motivations for restricting access and filtering content. Below are a few high-profile examples.

China
When most people think of internet censorship, China springs to mind. This makes sense as the country has a small army (upwards of 50,000 people) monitoring internet activity at all times. Also, much like Egypt, the government forces all online traffic through a mere three central routing systems. This makes it easy for censors to sift through all data entering and leaving the country.

China’s censorship apparatus is so advanced, it can take a very granular approach to repression and enforcement.

Turkey
The country’s swelling blacklist of 100,000 websites, coupled with harsh penalties for any whiff of anti-government sentiment, have created an extremely restrictive environment for Turkish internet users.

Ethiopia
In 2016, the government of Ethiopia blocked access to social networking sites to prevent cheating during the university entrance exam period.

North Korea
Unauthorized surfing of the internet is a dangerous activity in the Hermit Kingdom. The primary smartphones, tablets, operating systems, and browsers used in the country were all developed by the government, and content on the 5,000 or so accessible websites is tightly controlled.

Slipping Through the Firewall

Even when censoring measures are pervasive and effective, people continually find ways to slip between the cracks. For years, people have used proxy servers and virtual private networks (VPNs) to access content beyond their country’s censorship wall, but censors are getting better at discovering proxy servers and simply blocking them as they would any other site.

As a result, newer techniques are gaining popularity:

Steganography
Steganography is the science of hiding information. Basically, an innocuous file like an image can be stealthily encoded with information to evade detection by censors. Even changing a single pixel on a series of images can be used to relay a message, provided the recipient knows what to look for.

Refraction Networking
This circumvention tool uses partnerships with ISPs and other network operators to provide Internet freedom to users. Rather than trying to hide individual proxies, whole networks outside the censored country can become a conduit for the free flow of information.

Ranked: Largest Semiconductor Foundry Companies by Revenue

Most of the 10 largest semiconductor foundries in the world, are headquartered in just three Asian countries, accounting for 90% of the entire industry’s revenue.

A cropped chart showing the largest semiconductor foundry companies by their percentage of global revenues in Q1 2023.

Ranked: Largest Semiconductor Foundry Companies by Revenue

They’re in our phones, cars, planes, and even fridges.

Semiconductor chips have become critical for the modern way of life, and the biggest semiconductor foundry companies rake in billions of dollars from widespread demand.

This chart shows the largest semiconductor foundry companies by their percentage of global revenues in Q1 2023, using data sourced from Trendforce.

ℹ️ We highlight data for companies that only operate foundries (fabrication plants) that manufacture chips for clients, also known as a “pure-play” foundries, as well as companies that design and manufacture their own chips, known as integrated device manufacturers. “Fabless” manufacturers that only design and don’t manufacture their own chips are not included.

Semiconductor Foundry Companies by Revenue

At the top of the list and dwarfing every other company by revenue share is TSMC which earned 60% (or nearly $17 billion) of the entire industry’s revenue in Q1 2023.

Founded in 1987, TSMC is a pure-play foundry that has become Taiwan’s largest company and manufactures products for a host of clients including Apple, NVIDIA, and AMD.

Note: Revenue based on the following conversion rates: USD 1 = WON 1,276; USD 1 = NTD 30.4.

Well behind TSMC in foundry revenues is integrated device manufacturer Samsung, the biggest company in South Korea, which made $3.4 billion (12.4% of the industry’s revenue) from its semiconductor manufacturing business.

GlobalFoundries from the U.S., UMC from Taiwan and SMIC from China round out the top five, with each taking home around 6% of industry’s revenue share in Q1 2023. The former spun out from AMD’s manufacturing arm when the company went fabless in 2009.

Industry concentration is apparent in semiconductors. For example, the top 10 semiconductor foundry companies account for 98% of the entire industry’s revenue. Furthermore, 90% of the market is dominated by companies in just three Asian countries: Taiwan, South Korea, and China.
