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.

Visualizing the Critical Metals in a Smartphone

Smartphones can contain ~80% of the stable elements on the periodic table. This graphic details the critical metals you carry in your pocket.

Visualizing the Critical Metals in a Smartphone

In an increasingly connected world, smartphones have become an inseparable part of our lives.

Over 60% of the world’s population owns a mobile phone and smartphone adoption continues to rise in developing countries around the world.

While each brand has its own mix of components, whether it’s a Samsung or an iPhone, most smartphones can carry roughly 80% of the stable elements on the periodic table.

But some of the vital metals to build these devices are considered at risk due to geological scarcity, geopolitical issues, and other factors.

Smartphone PartCritical Metal
Touch Screen indium
Displaylanthanum; gadolinium; praseodymium; europium; terbium; dysprosium
Electronicsnickel, gallium, tantalum
Casingnickel, magnesium
Battery lithium, nickel, cobalt
Microphone, speakers, vibration unit nickel, praseodymium, neodymium, gadolinium, terbium, dysprosium

What’s in Your Pocket?

This infographic based on data from the University of Birmingham details all the critical metals that you carry in your pocket with your smartphone.

1. Touch Screen

Screens are made up of multiple layers of glass and plastic, coated with a conductor material called indium which is highly conductive and transparent.

Indium responds when contacted by another electrical conductor, like our fingers.

When we touch the screen, an electric circuit is completed where the finger makes contact with the screen, changing the electrical charge at this location. The device registers this electrical charge as a “touch event”, then prompting a response.

2. Display

Smartphones screens display images on a liquid crystal display (LCD). Just like in most TVs and computer monitors, a phone LCD uses an electrical current to adjust the color of each pixel.

Several rare earth elements are used to produce the colors on screen.

3. Electronics

Smartphones employ multiple antenna systems, such as Bluetooth, GPS, and WiFi.

The distance between these antenna systems is usually small making it extremely difficult to achieve flawless performance. Capacitors made of the rare, hard, blue-gray metal tantalum are used for filtering and frequency tuning.

Nickel is also used in capacitors and in mobile phone electrical connections. Another silvery metal, gallium, is used in semiconductors.

4. Microphone, Speakers, Vibration Unit

Nickel is used in the microphone diaphragm (that vibrates in response to sound waves).

Alloys containing rare earths neodymium, praseodymium and gadolinium are used in the magnets contained in the speaker and microphone. Neodymium, terbium and dysprosium are also used in the vibration unit.

5. Casing

There are many materials used to make phone cases, such as plastic, aluminum, carbon fiber, and even gold. Commonly, the cases have nickel to reduce electromagnetic interference (EMI) and magnesium alloys for EMI shielding.

6. Battery

Unless you bought your smartphone a decade ago, your device most likely carries a lithium-ion battery, which is charged and discharged by lithium ions moving between the negative (anode) and positive (cathode) electrodes.

What’s Next?

Smartphones will naturally evolve as consumers look for ever-more useful features. Foldable phones, 5G technology with higher download speeds, and extra cameras are just a few of the changes expected.

As technology continues to improve, so will the demand for the metals necessary for the next generation of smartphones.

Which Companies Belong to the Elite Trillion-Dollar Club?

Only a few companies have broken the 13-digit market cap barrier to join the $1T+ club. Who’s a member, and who’s hot on their heels?

Which Companies Belong to the Elite Trillion-Dollar Club?

Just a handful of publicly-traded companies have managed to achieve $1 trillion or more in market capitalization—only six, to be precise.

We pull data from Companies Market Cap to find out which familiar names are breaking the 13-digit barrier—and who else is waiting in the wings.

Footnote: All data referenced is as of August 17, 2021.

The Major Players in the Game

Apple and Microsoft are the only two companies to have shattered the $2T market cap milestone to date, leaving others in the dust. Apple was also the first among its Big Tech peers to ascend to the $1 trillion landmark back in 2018.

CompanyValuationCountryAge of company
Apple$2.48T🇺🇸 U.S.45 years (Founded 1976)
Microsoft$2.20T🇺🇸 U.S.46 years (Founded 1975)
Saudi Aramco$1.88T🇸🇦 Saudi Arabia88 years (Founded 1933)
Alphabet (Google)$1.83T🇺🇸 U.S.23 years (Founded 1998)
Amazon$1.64T🇺🇸 U.S.27 years (Founded 1994)
Facebook$1.01T🇺🇸 U.S.17 years (Founded 2004)

Facebook dipped in and out of the $1T+ club in July 2021, and continues its capricious movement. With just 17 years under its belt, it’s the youngest company ever to reach this valuation milestone—though not without some wild rides along the way.

State-owned oil and gas giant Saudi Aramco is the only non-American company to make the trillion-dollar club. This makes it a notable outlier, as American companies typically dominate the leaderboard of the biggest corporations around the world.

Who Else Might Join the Trillion-Dollar Club?

Companies with a market capitalization above $500 billion are also few and far between. Within this next list of six companies, the world’s most valuable automaker Tesla is another strong candidate to eventually join the Four Comma Club.

As per usual, analyst views on Tesla are quite varied. That said, some on Wall Street are predicting that Tesla might reach $3 trillion in market cap within the decade, owing to significant current and projected demand for electric vehicles (EVs) and driverless systems.

CompanyValuationCountryAge of company
Tesla$659B🇺🇸 U.S.17 years (Founded 2003)
Berkshire Hathaway$655B🇺🇸 U.S.182 years (Founded 1839)
TSMC$576B🇹🇼 Taiwan34 years (Founded 1987)
Tencent$537B🇨🇳 China23 years (Founded 1998)
Visa$515B🇺🇸 U.S.63 years (Founded 1958)

Visa, one of the pioneers of consumer credit in the United States, continues to innovate even 63 years after its founding. In attempts to expand the reach of its already massive payments ecosystem, Visa is experimenting with acquisitions, and even dipping its toes into cryptocurrency with some success.

Whether the next company to join the trillion-dollar club comes from the U.S., from the tech industry, or out of left field, it’s clear that it has some pretty big shoes to fill.
