Facebook, the biggest social network in the world, has announced many new featuresat the Facebook F8 conference developer last week.

Those changes affect the personal use, with the introduction of the “Timeline” as a new profile, and the ticker, which showcases everything happening in your network but only in a small box, while the posts from your closest connections are showcased in the main newsfeed.

The timeline is well designed, graphic and allows to access easily and fast the activity of someone in the past few years. It encourages users to post more information, but will trigger many concerns regarding privacy.

Facebook is also becoming kind of media hub, with applications related to music (Spotify, Soundcloud), Movies/TV (Netfix, TV) and News (The Guardian, The Washington Post, Yahoo news). Using those apps, you will consume content directly from your Facebook dashboard, and your activity will be showcased on the ticker of your connections. This is a big step in “social entertainment”, as the content provided to you will be filtered by your friends. But once again, many concerns about privacy rise: we don’t always want our friends to know what we read, watch or listen. This package of new features is a major shift in Facebook strategy : we used to share something on Facebook, it will be automatic now, positioning Facebook as a major platform for entertainment and information.

Applications related to lifestyle (sports, cooking etc) will also be launched and will allow you to share what you do: how long you’ve been running, what you have cooked etc. These new features will be very useful for brands, as they will create new information to target people.

So, Facebook is once again totally new, and brands will have to adapt to these changes.
New information will be available for brands, behaviour on Facebook will change, Fanpages will also probably change too (it is not the case for the moment yet).

The ticker for example changes totally the way brands interact with customers for the moment, as they don’t appear in the Home newsfeed anymore

But as the activity on Facebook becomes richer and more automatic, the possibilities for brands are expanding and they will probably have to think bigger
