If you bought a smartphone in 2011 — and didn’t buy a PC — you were part of a history-making trend.

For the first year ever, total PC sales around the world were outpaced by total smartphone sales, in units at least, according to data released Friday by market analyst firm Canalsys. Nearly 488 million smartphones were shipped, compared to just (just!) 415 million PCs.

News of Facebook‘s IPO swamped the Internet earlier this week, when the company’s 213-page S-1 document went up on the SEC’s website, promptly crashing it.

In addition to confirming previous reports that the filing was imminent, the document contained numerous interesting facts that many have long been wondering, such as the company’s revenue, how much Mark Zuckerberg makes, and who the company’s highest-paid employees are.

There were also several key company insights disclosed, such as the factors that Facebook considers to be risks.

Travel is so much easier when you’re prepared and know what to expect. Airfare shopping website CheapAir.com now lets you find out which flights offer Wi-Fi, live TV and movies before you book.

Onboard technology can make flying a much more pleasurable and productive experience. But unless you book with a particular airline that offers Wi-Fi on every flight, you’re not guaranteed these services. There is often little or no difference between the price of flights with or without WiFi and live TV — but the difference in experience can make or break your flight.

Century 21 has enlisted a team of celebrities for its first-ever Super Bowl commercial.

Reality TV star and business mogul Donald Trump, Pro Football Hall of Fame member Deion Sanders and Olympic speed skater Apolo Ohno will help showcase what Century 21 feels are the primary characteristics of the company’s agents: “Smarter. Bolder. Faster.”

In the 30-second ad, which will air Sunday on NBC during a third-quarter commercial break, the trio is seen participating in the home-buying and home-selling process as a Century 21 agent one-ups each of them.

Genius Idea: A new way to organize your wardrobe and track your spending.

If you’re like me, your sense of your wardrobe is slightly nebulous. You might be able to recall half the brands and items in it, but you wouldn’t be able to tell me, for instance, how often you wear pencil skirts compared to A-line skirts, or whether you tend to wear Banana Republic clothing more often with accessories from J Crew or HM.

In 2010, branded content was one the largest trends among retailers and brands. In 2011, branded content shifted to branded entertainment. Now, in 2012, we’ll look toward content cultivation and aggregation.

By creatively using Pinterest and Tumblr, brands are becoming enthralled with consumer curation, primarily because these types of curated sites create non-linear paths to purchases.

If you’re not aware of Kim Dotcom, the man who changed his last name to pay homage to the World Wide Web, we offer you this brief history lesson. Born in Germany, Kim Schmitz (a.ka. King Kimble, a.k.a. King of the Kimpire, a.k.a. The Kim-pin), is a larger-than-life Internet hustler who hauled in money hand-over-fist by creating Megaupload, a site that essentially allows — er, allowed — people to share copyrighted content.

Crowd-sourced social photo sharing appears to be the latest community engagement trend among professional sports teams, largely powered by the online startup Olapic.

Olapic’s service allows organizations to quickly and easily enable fans, readers or other types of audiences to submit photos of their own experiences at a game or event. Members of a crowd use social networks to submit their photos to the larger organization. The photos are then automatically collected on a subdomain and published after a moderator approves them. No new site, no new laborious curation process.

Companies that rely on a visual or photographic web presence often find it difficult to convey their media on Twitter. Take, for instance, apparel brands that need to get social media eyes on their merchandise, or a design firm that seeks exposure. How can these types of businesses ensure that Twitter followers see their wares?

Ecommerce or design companies may prefer Facebook, due to its inherently visual and expansive nature. However, businesses these days can’t afford to bypass Twitter entirely — especially because many people keep their Twitter feeds open all day long.

Apple has updated the End User Licensing Agreement (EULA) for its iBooks Author app, clarifying its terms and ownership conditions.

Immediately after its release, the EULA for iBooks Author was torn apart by the tech press and copyright analysts. The original wording stated that authors would only be able to sell books created in iBooks Author in Apple’s iBookstore.

The broadness of the terms made it appear Apple was claiming ownership of the content generated in iBooks Author.

With the 1.0.1 update [Mac App Store link], the language in the EULA is now much more clear on what Apple’s actual policies.

Virgin Galactic, the aspiring space tourism company founded by Sir Richard Branson, is on track to begin powered test flights of its spaceship this summer, with the goal of starting passenger flights in 2013.

Virgin CEO George Whitesides discussed the coming test flights at a meeting in January with the Aerospace Defense Forum. The coming test flights mark the first time the spacecraft, SpaceShipTwo will fire the actual rocket that it will use to fly into sub-orbit, 60-plus miles above the Earth.

Social and mobile technologies aren’t just important for guerilla marketing campaigns and grassroots outreach.

They’re also changing how the world’s biggest broadcast media companies do business.

Mashable recently spoke with top executives and personalities from the sports behemoth ESPN during the company’s biggest week of the year for Super Bowl XLVI. The interviews reveal how the evolution of digital impacts the original mass broadcast medium — what is traditionally thought of as “radio.”

Perhaps nothing shows the shifting landscape better than a recent name change for ESPN’s audio division. Until about three years ago, the entire division — the company’s second-most consumed medium, behind its ubiquitous television presence — was known simply as ESPN Radio.

Stephen Colbert asked his fans to share his passion for space by donating to NASA to support its work with the International Space Station.

Colbert rallied behind NASA’s efforts to create alternative vaccines to fight diseases — including salmonella and pneumonia — that have become increasingly resistant to antibiotics.

“I love looking up at the stars and wondering what distant planets are still out there and to be discovered and can we frack them for methane,” Colbert joked in his public service announcement released on NASA’s website on Thursday.

Anonymous is on the move. The hacker group has claimed credit for coordinated attacks and leaks against the U.S. government and international law enforcement agencies Friday. According to Twitter accounts associated with the group of “hacktivists,” more activity can be expected throughout the day.

Anonymous released a call between the FBI and Scotland Yard regarding a joint effort in a cybercrime case. The case is tied to investigations in New York, Baltimore and Ireland, according to The Guardian. Anonymous posted the recording online for public access with some names censored from the tape but a later leak included the names and contact information of the alleged participants.

SCHEDit wants to answer the question “what is going on tonight?” in the same way that Twitter answers the question “what is happening?” — with a customizable, interest-based platform that transcends personal preference.

The company launched with its first partner, Boston.com, on Thursday.

Here’s how it works: Users log into a new events site on Boston.com with their Facebook accounts. They set up a profile and choose specific venues and people who they want to follow. Their newsfeeds are then populated with events that those venues are hosting and that those people have said they’ll attend.

Facebook users receive more comments, messages and likes — the hugs and high-fives of social networking — than they give, according to a new study.

The Pew Research Center’s Internet American Life Projectstudy, which looks at Facebook activity of users over a one-month period, shows that users Like content on their News Feed about 14 times, while their content is Liked about 20 times. Users send about nine personal messages and receive 12.

This discrepancy exists because certain “power users” dominate one kind of Facebook action. Meaning everyone has friends that excessively tag photos, send messages or “like” things all the time. Others obsessively “friend” people.

The Huffington Post Media Group revealed more details about its upcoming online news channel, the Huffington Post Streaming Network.

The announcement takes place just days before Huffington Post celebrates its first anniversary since its acquisition by AOL.

At a press event previewing the Streaming Network, Huffington celebrated the results from its first year under the AOL banner.
