It's Official: Facebook is Now Public

The long-awaited social networking IPO is now here. Are you excited? After a lengthy delay this morning, Facebook FB -- the world's largest social network -- has become a public company. Co-founded by Mark Zuckerberg and launched during the winter of 2004, Facebook was the first company to solidify social networking as a viable industry. It proved that social media was more than a fad. It also showed the world that, when used properly, social networks can be a great tool for advertising. Valued at roughly $100 billion and priced at $38 a share, Facebook opened today at $42.05. It is easily the most anticipated IPO of the year. In the coming hours, we will finally know if that anticipation is strong enough to ignite a powerful investor response. Follow me @LouisBedigianBZ
