LinkedIn turned ten years old on Sunday. It’s hard to believe it’s been a decade, but believe it or not, the professional social network launched all the way back in 2003. It has come a long way in the meantime.

The company has put together an interesting visual timeline that you can peruse here. It begins in 2002 when Hoffman recruited a team of old colleagues from SocialNet and PayPal to work on the idea that would eventually become LinkedIn. In the early days, they were sometimes getting as few as 20 signups a day.

In 2009, Jeff Weiner joined as President, and would then become CEO, a title he currently holds. Two years later came the IPO.

Reid Hoffman writes on the LinkedIn blog:

Ten years ago, I co-founded LinkedIn in my living room with the mission of connecting the world’s professionals to make them more productive and successful. Inspired by the invaluable role relationships played in our own careers, we launched LinkedIn with the tagline “Relationships matter.”

At the end of our first month, we had 4,500 members in the network. 10 years later, we’re honored and humbled that so many of you have made LinkedIn a part of your daily professional lives.

Today, hundreds of millions of professionals around the world are turning to LinkedIn to connect with each other, manage their identities, get insights they need to be great at what they do, and find their dream jobs. I’m continually inspired by our members’ career aspirations and achievements.

LinkedIn currently boasts 225 million members, and says it is growing by a rate of two members every second.

The company’s stock is up 0.23% in pre-market trading.
