(CNN) -- It's been a remarkable year when it comes to technological breakthroughs and how we consume technology on a daily basis.

As we round out the end of another decade, we saw as social networking sites like Facebook and Twitter radically changed the way we communicate with each other.

Today, Facebook has more than 350 million users around the world that use the site to share photos and video, and who communicate with each other through wall posts and status updates.

This year we saw as Facebook brought down Simon Cowell's "X-Factor" juggernaut for the Christmas number one in the U.K.

A Facebook group with more than one million members helped Rage Against the Machine beat "X-Factor" winner Joel McElderry for the top Christmas spot.

What was your favorite tech gadget of 2009?

The other important social networking site of the year was Twitter.

The micro-blogging site took off in 2009 and the term "tweet" became synonymous with updating your page.

After this summer's unrest in Iran, the site proved especially useful as many people in the country used Twitter to post pictures and videos of the protests.

Twitter was also the first place where images of the Hudson River plane crash in New York City surfaced.

Another big trend in 2009 was the importance of video sharing sites like YouTube.

The site passed a major milestone this year as more than one billion videos were viewed online each day.

The site also helped launch the careers of people like Susan Boyle -- more than 120 million people watched her "Britain's Got Talent" audition online.

As far as gadgets are concerned, there weren't any real stand outs, but the one winner here was probably smart phones.

The Apple iPhone took one of the top spots as the new 3GS version was released earlier this year offering users faster connectivity, better applications and a higher quality camera.

In terms of what to look forward to in 2010, the big innovation to watch is something called augmented reality.

Enabled by GPS technology, augmented reality uses your mobile phone's camera to overlay information on the environment around you.

So, if you're pointing your camera at a restaurant, the technology will allow you to read reviews or find information while you walk past.
