Let me be honest. I didn't even have a vague plan of writing this very blog post. The actual idea was to list all the products, services, and apps by Facebook --- just like I did Over 271 Google Products & Services You Probably Don’t Know. And I even started writing this blog post with the title "Over 51 Facebook Products & Services You Probably Don’t Know" only to realize later that they don't even have 21 standalone products (including web and mobile apps). Nevertheless, I'm listing all the products and services and apps offered by Facebook. And you will see that Facebook's dominance comes from just three products apps. Facebook. WhatsApp. Instagram. As you know, Facebook is the single largest social network out there and is also the second most popular website on the web according to Alexa Top 500 Global Websites (the first being Google + YouTube). Facebook is not the first social network and yet it's dominating the web 2.0. Just like Google did. Google wasn't the first search engine out there, but it managed to change the way we used the web. Google changed the way we gathered information, and it changed the way we spend our time online. Facebook did the same. It changed the social networking scene forever and at the same time it crushed several other social networking websites (MySpace, Orkut, Friendster, Hi5, to name a few) and several mobile apps. So today, I'm listing all the products and services and apps by Facebook. And I will be updating this article as they launch more products or make more acquisitions.
