"Selfie," one of the words that defined the decade aren't all bad. I just can't say the same for selfie sticks.


The decade we know as the 2010s is in its final days. Over the past few months, as part of CNET's Decade in Review, we've looked back at the last 10 years with retrospectives including the best films of the decade, the top memes, the worst tech trends and 50 incredible people who left us.


Now I present 25 words, phrases and terms that tell the story of tech since 2010. Some explain deeply complex topics and others, well, are a bit frothier. So break out your dictionary and start marking in the margins, because these are the words added to our lexicon, or gaining new relevance. (And if you're a wordsmith, I have a list of the decade's top quotes as well.) Of course, there are many more buzzwords I didn't cover, so list your suggestions in the comments.


In computing terms, this means a set of rules or a step-by-step process for performing a task. As a word it's far older than the decade we're finishing, but it's gained notoriety over the past few years as the influence of social media has grown. Companies such as Facebook and Twitter use algorithms to determine which posts they present to you and in what order. Or in YouTube's case, an algorithm decides which videos are in the "Up Next" box. Most of the time these algorithms work well, but they're also being blamed for presenting hoax news stories, creating filter bubbles (where you only see information that reinforces your beliefs) and recommending videos with hateful content. In response to the criticism, some services have tweaked their algorithms to give their users more control over what content is shown.

Robots like Sophia are an obvious example of AI, but the technology is far more extensive.

Artificial intelligence

Like CNET's Jon Skillings, I'm going to defer to John McCarthy, the man who coined the term, to define it. He described artificial intelligence as "the science and engineering of making intelligent machines, especially intelligent computer programs." By "intelligent machine," he meant machines that can mimic things the human mind can do, such as solving problems or learning new information and adapting to it. And I'm not just talking about robots. Examples include self-driving cars and voice assistants (see below), but the topic is also controversial (as in, AI could have the power to end humanity). Machine learning is the branch of AI that teaches computers to learn tasks or recognize patterns on their own, while deep learning is an area of machine learning that's about recognizing relationships in data.

Language naturally evolves and expands over time, adding new words, changing the meaning of others and sending others still to the vocabulary pasture. And during the 2010s, one of the most common words in the English language expanded to a new part of speech when "because" became both a conjunction and a preposition. Today there's no need to follow it with a pesky excess word like "of." Rather, just follow it with an appropriate noun, like "I was late because sleep." It's also a way to conveniently explain complex topics in an ambiguous way. "Dark matter exists because science!" And it's a way to be ambiguous about simple topics. For example, "I didn't finish doing that because reasons" is especially popular.


Netflix: Perfect for binge watching and chilling. 

Angela Lang/CNET

Binge watching

Especially popular with streaming content, which is programming that's delivered over the internet rather than a traditional cable channel, this is the viewing of several episodes of a television program (or parts of a film franchise) in rapid succession. Binge watching is also possible with DVDs or content saved on a DVR. Though Netflix content is binge-watchable, Netflix and chill has a, well, different meaning. It's actually a euphemism for hooking up (though I suppose you could watch an episode or two before the sex). It was true even in the pre-Netflix era: As Dorothy Zbornak wisely said in a 1986 episode of The Golden Girls, "Honey, beware of anybody who says 'no calories,' 'absolutely no charge' and 'let's just lie on the bed and watch television.'"

Security cameras with facial recognition tech inside

It may sound like something you'd hear on a wellness retreat, but biometrics is the ability to identify a person through behavioral or physical characteristics. This could include fingerprint sensors, voice recognition, iris scanning and facial recognition. Examples of biometrics-equipped technology are the iPhone's Face ID feature and, more controversially, cameras in public areas that could be used by law enforcement to track people as they move around a city. Some cities have banned the practice, but it may already be at an airport near you (complete with a racial bias).

Watch this: Bitcoin: A beginner's guide


Gosh, this is a hard one. That's why I'll rely on my more knowledgeable colleague Stephen Shankland to explain. As he puts it, a blockchain is an ever-growing set of data blocks with each block recording a collection of transactions (such as the date, time and amount of a purchase). But instead of all of those blockchains being stored on a single computer (like a company server), they're distributed across a group of computers. It could be thousands of them, and each computer has its own copy of the transaction. Most important, blockchain makes cryptocurrencies like bitcoin possible. Because cryptocurrencies are digital, decentralized currencies without a government, bank or other authority to control them, blockchain is used to verify transactions. And because blockchain is an encryption technology, transactions using cryptocurrency are anonymous. That's why it's popular on the dark web, which refers to any part of the internet that isn't discoverable by a search engine.


Computational Photography makes it possible to take highly detailed shots after dark, like this with the iPhone 11 Pro's Night Mode.

Computational photography

Again, I'll let Mr. Shankland take the wheel. As he writes, computational photography is "digital processing to get more out of your camera hardware -- for example, by improving color and lighting while pulling details out of the dark." But it's not only present in pricey DSLR cameras -- you need to look no further than many camera phones to see how computational photography works. Examples include an HDR mode, where a camera takes two or more photos at different brightness levels and then merges the shots into a single photo, and the night modes on both the Pixel 3 and iPhone 11.

Cord cutter

Everyone hates their cable company, right? Well, cord cutters channel that loathing into action by ending their cable TV service (note that actual cutting of cord isn't necessary). Instead of paying Time Warner for TV content, cord cutters get their television through streaming video services such as Netflix and Amazon Prime. The upside includes lower subscription costs and being able to tell Comcast to suck it. The downside includes still needing to pay for internet (maybe through that same cable company), subscription fatigue (since you have to pay for each service individually) and the danger that you may miss some live TV events. So think before you cut

You hear this a lot at startups, especially when they're pitching to a venture capital firm to get funding. But it applies to established companies as well (remember Facebook's motto of "Move fast and break things"?). Disruption occurs when a company introduces a product or service with the aim of radically changing or even replacing an existing industry. Airbnb and Uber are classic examples because they've created new competition for hotels and taxis. Though disruption is seen as a point of pride, such companies are also criticized for not owning the damage done by their treasured disruption. Airbnb, for example, is now blamed for driving up housing costs and displacing long-term residents in popular tourist cities

Watch this: We're not ready for the deepfake revolution


A troubling development over the last few years, deepfakes are the video version of a photoshopped picture. They're video forgeries that make people seem to say or do things they didn't. Essentially, it's grafting the face of one person onto the body of another person, but in a way that's so real looking, it's hard to tell that it's not. Not only is a person's face duplicated (made possible through facial recognition technology), but their voice can be as well (thanks to machine learning). Though deepfakes can be harmless and even fun if they're identified as such, they also could be incredibly destructive. Politicians could be depicted as saying something racist, obscene or weird -- earlier this year a doctored video of House Speaker Nancy Pelosi went viral -- or a person might find themselves unexpectedly depicted in porn.


Emojis show that pictures can say a thousand words.

Angela Lang/CNET


An evolution of the emoticon (remember the smiley?) that originated in Japan, emoji are images commonly used in texting, chat programs and social media to convey a specific word or meaning. Examples of emoji (the word is both singular and plural), which run into the hundreds, include a thumbs up (or down), faces with various expressions and the popular eggplant. The style of emoji can differ between platforms, but there's a consortium that approves and standardizes them. Acceptable in both personal and business communication, they can save typing time when you're in a hurry. And who knows... one day they may be the only way we communicate. The release of new emoji is eagerly anticipated. I mean, how long did we wait to get a taco?

2020 Porsche Taycan 4S OGI

Even Porsche makes an EV with its Taycan 4S.



Thirteen years ago we were asking, "Who killed the electric car?" But today electric vehicles are everywhere. And it's not just Tesla, even if Elon Musk's company gets most of the hype. BMW, Chevrolet, Nissan and Toyota (among others) all make EVs, too. Another term that's come about as electric cars became mainstream is range anxiety, which refers to a driver's fear that their EV won't have enough battery to reach a destination.

Yes, this has become a real job at which people can make millions. Sigh ... but enough Gen X griping. Though "influencer" primarily refers to something that influences something else, its contemporary definition is a person with the power to change opinions or drive behaviors of a large audience online, primarily through social media (Instagram in particular). They can encourage their fans to buy products through endorsements, rally for a political candidate or generate hype for a failed music concert in the Bahamas. Influencers can include established celebrities such as actors, musicians and athletes, but they also can be people with shorter CVs who are famous simply for being famous. Subsets of influencers are YouTubers (a person on YouTube), streamers (someone who livestreams their content rather than precording it), VSCO girls (young woman who edit their Instagram photos in an app called VSCO) and Instagays (attractive and musclebound gay men who live a fabulous life online, when the reality may be anything but).

Internet of Things

This refers to the trend of connecting everyday items to the Internet. A linchpin for the concept of the smart home, IoT devices can include doorbells with cameras that you can view while at work, thermostats you can control remotely and refrigerators that order your groceries for you. The list of possibilities is endless, and it isn't limited to products that predated the internet. Some IoT devices, like voice assistants (see below) exist only because they have an online connection. While IoT gadgets can bring convenience, there's a robust debate over whether they're vulnerable to hacking

As a hashtag it flourished in 2017 following the exposure of widespread sexual assault allegations against film producer Harvey Weinstein. At the height of the media coverage, actor Alyssa Milano encouraged victims of sexual assault to tell their stories on Twitter. Many people did, both celebrities and not, in the United States and around the world. But as an expression, "Me Too" started 11 years before the hashtag went viral. Civil rights activist Tarana Burke, who was sexually assaulted as a child and a teenager, started the Me Too Movement in 2006 to support survivors of sexual violence.


A protester argues for net neutrality at a 2017 demonstration in New York.

Net neutrality

You've heard this one a lot lately, I'm sure. Net neutrality is the principle that all traffic on the internet, whether it's from Facebook , Amazon, the Los Angeles Times or a local startup, should be treated equally by wireless and broadband service providers. In other words, the company that delivers your Internet connection can't can't block, slow down or charge extra for some content while favoring others. In 2018, despite widespread opposition, a Republican-led FCC repealed Obama-era rules mandating federal net neutrality rules set in 2015. The DC Circuit Court of Appeals upheld the repeal in October while striking down a key provision that blocked states (like California) from passing their own net neutrality protections.

Ride hailing

Buckle in, this one is a bit complicated. I was about to define it incorrectly, before CNET Senior Reporter Dara Kerr steered me straight. Ride hailing refers to companies like Uber and Lyft, which provide point-to-point transportation services via car. While Uber and Lyft perform a similar service to traditional taxis, you hail them only through an app and you pay your fare directly to the company, rather than to the driver. (As CNET classifies them, taxis are not a ride-hailing service even though you can hail them on the street.) Though both Uber and Lyft refer to themselves as ride-sharing services, that's just marketing-speak. Because unless you're in an Uber Pool, you're not really sharing the ride with anyone (the driver and other people in your party don't count). But either way, Uber as a company has become so widespread that its name is now used as a verb: "I'll Uber it over to your house."


When just your phone won't do for a selfie, use a drone instead.

Sarah Tew/CNET


Back when I reviewed phones in the last decade, we called these "vanity shots" (a more accurate term, I think). But whatever you call them now, these photos of yourself, taken with the second camera on your phone, are both a blessing and a curse. Sure, you don't have to ask someone to shoot you and your friends in front of the Tower of London or with a celebrity, but selfie takers, eager for their Instagram-worthy shot, have ruined landscapes, killed animals, shattered monuments and destroyed art. Some selfie-takers have even died in the process. And then there's the dreaded selfie stick. Variations include groufie (a selfie of a large group), dronie (a selfie taken by a drone), belfie (a "bottom selfie," or a photo of your toned bum), welfie (a selfie with material items to show your wealth) and slofie (a short slow-motion selfie video on the iPhone 11).


Gig economy workers have advocated for better pay as the sharing economy has boomed.

Dara Kerr/CNET

Sharing economy

This is an economic concept in which assets are shared by a group of people. The assets, such as a flat rented on Airbnb, typically are privately owned but are made available through others to use through peer-to-peer transactions via online platform. A related concept is the gig economy, in which people offer a service to a company on a part-time basis. Ride-hailing and some delivery drivers (for companies like Postmates) are considered gig economy workers, but so are freelance writers and photographers. As the gig economy has grown, the treatment of gig workers has fallen under scrutiny. Because they're not considered full-time employees, pay can be low and they're not entitled to benefits like health insurance, despite long working hours.

Swipe right to say yes, left to say no.

College Humor

Swipe right

On the dating apps Tinder and Bumble, a user swipes right on a potential date's photo to show they're interested and swipes left to show they're not. But the term has graduated beyond the apps to describe your acceptance of pretty much anything, from a person to a hamburger to a car. "I'd swipe right on those shoes."

Tech bro

A pejorative variation on the word "bro," or a stereotypical alpha male guy, tech bro describes a subset of men who work in the technology industry. Characteristics include newfound wealth through an IPO, a brash confidence and sense of entitlement, talking loudly about subjects they may know little about and a propensity toward sexism by promoting a "boys' club" working culture. Outside the office they can be found gentrifying a neighborhood while inflating real estate prices and obsessing about craft beer in dull, lookalike bars. Brogrammers are tech bros who code, and pharma bros, including convicted fraudster Martin Shkreli, work in the pharmaceutical industry.

Trump takes agressive stance against CNN through Twitter

President Trump is a frequent tweetstormer. 



This is a series of tweets in rapid succession used to convey a long message beyond Twitter's 280-character limit (also true when tweets were just 140 characters). A person can use a tweetstorm to tell long stories, state a detailed opinion or make an impassioned argument. Proper tweetstorms break each tweet in the storm into complete sentences and clearly indicate how many tweets are in the storm. But not everyone does it that way.

Watch this: What is AR and how does it differ from virtual reality?

Virtual reality

It predated the decade, but the 2010s brought the term mainstream with actual products. As you might guess, virtual reality replaces the real world with a completely virtual one, whether it be the bottom of the ocean or a planet in the Star Wars universe. To make that happen, VR requires a person to wear a headset like the Oculus Go that completely blocks their view. Augmented reality is when you're looking at the real world, but it's enhanced or, ahem, augmented with other data. That can be accomplished through a pair of smart glasses like Microsoft's HoloLens or even through a game on your phone like Pokemon Go. As its name implies, mixed reality is a mix between the two. It projects virtual images onto the real world through the camera on a phone, tablet, glasses or headset, but also anchors them to a point in real space.

Sonos One

Voice assistants are in your phone and in smart speakers like these.

Sarah Tew/CNET

Voice assistant

Also known as virtual assistants or digital assistants, voice assistants use speech recognition software to interpret commands or questions from human voices and respond or answer accordingly. Because they listen to your command and then make a decision they "think" you want, voice assistants also use artificial intelligence and machine learning. They can perform a great number of tasks, from telling you the day's weather to composing an email to turning up the music on your stereo. Apple's Siri, Google Assistant, Samsung's Bixby and Amazon's Alexa are all examples of the technology. Smart speakers such as the Amazon Echo or Apple Homepod are internet-connected speakers integrated with voice assistants. But as with other smart home products, the digital security of smart speakers remains a critical issue. 


Let the hype machine commence. 5G is the fifth generation of wireless networking technology that wireless carriers around the world are beginning to build. Think of it as the child of 4G, the wireless technology you're using on your phone now, and the grandchild of 3G, a technology from a decade ago. Each generation of the wireless family is faster than the one before it and as a result can make new technologies possible. With a wireless experience that's 10 to 100 times faster than today's 4G networks -- as fast as 1 gigabit per second, or speedier than a fiber cable -- 5G promises everything from letting you download a full film in seconds over the air to making self-driving cars a reality.
