How Google Tracks You – And What You Can Do About It
Ever get the feeling you’re being watched?
It’s because you are – and for a rough proxy of this, use the browser extension Ghostery to see how many tracking scripts are watching you on a typical media site. (It doesn’t work for everything, but a large media site like Vice.com has 50+ trackers, with 40 of them focused on advertising).
Capturing this user data helps sites sell their inventory to advertisers, but a select few companies operate in this capacity at a whole different level. Google and Facebook are the best of examples of this, as nearly $0.60 of every dollar spent on digital advertising goes to them. They both have the sophistication and ubiquity to capture incredible amounts of information about you.
Google is Everywhere
Today’s infographic, which comes to us from Mylio, focuses in on Google in particular.
The search giant is massive in size, and there is a good chance you tap into Googleverse in some way:
- Global market penetration for Android is 61-81%.
- Google has a 78.8% market share for online search.
- The company generates $67.4 billion in annual ad revenue.
- Google processes two trillion searches annually.
- 30-50 million websites use Google Analytics to for tracking.
- There are 700,000 apps available in the Google Play store.
- 82% of videos watched online come from YouTube.
- In total, Google has at least 79 products and services.
According to Google’s documentation, it uses these services to pull out information on the “things you do”, “things you create”, and the things that make you unique.

All in all, Google tracks your activity history, location history, audio history, and device history. It also builds a profile for you for serving ads – age, gender, location, income, and other demographic data.
You can view and actually download this history by using a tool called Google Takeout.
Many people understand that their data helps support advertising revenues on websites they enjoy. Others are rightly concerned about their privacy, and how their information is used. Regardless of which category you fit in, becoming informed about how privacy on the internet works will help you craft an experience that best fits your preferences.
Visualizing the Power Consumption of Bitcoin Mining
Bitcoin mining requires significant amounts of energy, but what does this consumption look like when compared to countries and companies?
Visualizing the Power Consumption of Bitcoin Mining
Cryptocurrencies have been some of the most talked-about assets in recent months, with bitcoin and ether prices reaching record highs. These gains were driven by a flurry of announcements, including increased adoption by businesses and institutions.
Lesser known, however, is just how much electricity is required to power the Bitcoin network. To put this into perspective, we’ve used data from the University of Cambridge’s Bitcoin Electricity Consumption Index (CBECI) to compare Bitcoin’s power consumption with a variety of countries and companies.
Why Does Bitcoin Mining Require So Much Power?
When people mine bitcoins, what they’re really doing is updating the ledger of Bitcoin transactions, also known as the blockchain. This requires them to solve numerical puzzles which have a 64-digit hexadecimal solution known as a hash.
Miners may be rewarded with bitcoins, but only if they arrive at the solution before others. It is for this reason that Bitcoin mining facilities—warehouses filled with computers—have been popping up around the world.
These facilities enable miners to scale up their hashrate, also known as the number of hashes produced each second. A higher hashrate requires greater amounts of electricity, and in some cases can even overload local infrastructure.
Putting Bitcoin’s Power Consumption Into Perspective
On March 18, 2021, the annual power consumption of the Bitcoin network was estimated to be 129 terawatt-hours (TWh). Here’s how this number compares to a selection of countries, companies, and more.
|Name||Population||Annual Electricity Consumption (TWh)|
|All of the world’s data centers||-||205|
|State of New York||19.3M||161|
|Walt Disney World Resort (Florida)||-||1|

If Bitcoin were a country, it would rank 29th out of a theoretical 196, narrowly exceeding Norway’s consumption of 124 TWh. When compared to larger countries like the U.S. (3,989 TWh) and China (6,543 TWh), the cryptocurrency’s energy consumption is relatively light.
For further comparison, the Bitcoin network consumes 1,708% more electricity than Google, but 39% less than all of the world’s data centers—together, these represent over 2 trillion gigabytes of storage.
Where Does This Energy Come From?
In a 2020 report by the University of Cambridge, researchers found that 76% of cryptominers rely on some degree of renewable energy to power their operations. There’s still room for improvement, though, as renewables account for just 39% of cryptomining’s total energy consumption.
Here’s the share of cryptominers that use each energy type vary across four global regions.

and the Caribbean

Editor’s note: Numbers in each column are not meant to add to 100%
Hydroelectric energy is the most common source globally, and it gets used by at least 60% of cryptominers across all four regions. Other types of clean energy such as wind and solar appear to be less popular.
Coal energy plays a significant role in the Asia-Pacific region, and was the only source to match hydroelectricity in terms of usage. This can be largely attributed to China, which is currently the world’s largest consumer of coal.
Researchers from the University of Cambridge noted that they weren’t surprised by these findings, as the Chinese government’s strategy to ensure energy self-sufficiency has led to an oversupply of both hydroelectric and coal power plants.
Towards a Greener Crypto Future
As cryptocurrencies move further into the mainstream, it’s likely that governments and other regulators will turn their attention to the industry’s carbon footprint. This isn’t necessarily a bad thing, however.
Mike Colyer, CEO of Foundry, a blockchain financing provider, believes that cryptomining can support the global transition to renewable energy. More specifically, he believes that clustering cryptomining facilities near renewable energy projects can mitigate a common issue: an oversupply of electricity.
“It allows for a faster payback on solar projects or wind projects… because they would [otherwise] produce too much energy for the grid in that area”
– Mike Colyer, CEO, Foundry
This type of thinking appears to be taking hold in China as well. In April 2020, Ya’an, a city located in China’s Sichuan province, issued a public guidance encouraging blockchain firms to take advantage of its excess hydroelectricity.
Which Streaming Service Has the Most Subscriptions?
From Netflix and Disney+ to Spotify and Apple Music, we rank the streaming services with the most monthly paid subscriptions.
Which Streaming Service Has The Most Subscriptions?
Many companies have launched a streaming service over the past few years, trying to capitalize on the digital media shift and launching the so-called “streaming wars.”
After Netflix grew from a small DVD-rental company to a household name, every media company from Disney to Apple saw recurring revenues ripe for the taking. Likewise, the audio industry has long-since accepted Spotify’s rise to prominence, as streaming has become the de facto method of consumption for many.
But it was actually the unexpected COVID-19 pandemic that solidified the foothold of digital streaming, with subscription services seeing massive growth over the last year. Although it was expected that many new services would flounder along the way, media subscription services saw wide scale growth and adoption almost across the board.
We’ve taken the video, audio, and news subscription services with 5+ million subscribers to see who came out on top—and who has grown the most quickly—over the past year. Data comes from the FIPP media association as well as individual company reports.
Streaming Service Giants: Netflix and Amazon
The top of the streaming giant pantheon highlights two staples of business: the first-mover advantage and the power of conglomeration.
With 200+ million global subscribers, Netflix has capitalized on its position as the first and primary name in digital video streaming. Though its consumer base in the Americas has begun to plateau, the company’s growth in reach (190+ countries) and content (70+ original movies slated for 2021) has put it more than 50 million subscribers ahead of its closest competition.
The story is the same in the audio market, where Spotify’s 144 million subscriber base is more than double that of Apple Music, the next closest competitor with 68 million subscribers.
Meanwhile, Amazon’s position as the second most popular video streaming service with 150 million subscribers might be surprising. However, Prime Video subscriptions are included with membership to Amazon Prime, which saw massive growth in usage during the pandemic.
|Service||Type||Subscribers (Q4 2020)|
|Amazon Prime Video||Video||150.0M|
|Amazon Prime Music||Audio||55.0M|
|Tencent Music (Group)||Audio||51.7M|
|New York Times||News||6.1M|
Another standout is the number of large streaming services based in Asia. China-based Tencent Video (also known as WeTV) and Baidu’s iQIYI streaming services both crossed 100 million paid subscribers, with Alibaba’s Youku not far behind with 90 million.
Disney Leads in Streaming Growth
But perhaps most notable of all is Disney’s rapid ascension to the upper echelons of streaming service giants.
Despite Disney+ launching in late 2019 with a somewhat lackluster content library (only one original series with one episode at launch), it has quickly rocketed both in terms of content and its subscriber base. With almost 95 million subscribers, it has amassed more subscribers in just over one year than Disney expected it could reach by 2024.
|Service||Type||Percentage Growth (2019)|
|Amazon Prime Video||Video||100.0%|
|Amazon Prime Music||Audio||71.9%|
|Tencent Music (Group)||Audio||66.8%|
|New York Times||News||60.5%|
The Disney+ wave also spurred growth in partner streaming services like Hotstar and ESPN+, while other services with smaller subscriber bases saw large growth rates thanks to the COVID-19 pandemic.
The lingering question is how the landscape will look when the pandemic starts to wind down, and when all the new players are accounted for. NBCUniversal’s Peacock, for example, has reached over 30 million subscribers as of January 2021, but the company hasn’t yet disclosed how many are paid subscribers.
Likewise, competitors are investing in content libraries to try and make up ground on Netflix and Disney. HBO Max is slated to start launching internationally in June 2021, and ViacomCBS rebranded and expanded CBS All Access into Paramount+.
And international growth is vital. Three of the top six video streaming services by subscribers are based in China, while Indian services Hotstar, ALTBalaji, and Eros Now all saw surges in subscriber bases, with more room left to grow.
