There are many reasons as to why Facebook decided to rebrand, most people know that the public’s trust in the social platform has been at the lowest it has been in a few years (although it’s never been 100%).
Why have they done this?
As mentioned, the public’s trust in the social platform is at an all-time low, due to many theories. The public no longer feels that their data is safe within the platform after multiple data breaches that have chipped away at peoples trust.
Obviously, Facebook wants to grow back the trust again as they don’t want to lose 2.41 billion users! As most people know, Facebook own various popular social media platforms including Messenger, Instagram and Whatsapp. However, this seemed like another reason for them to rebrand as it was realised that many people didn’t know about their other ownerships.
With this in mind, unity between the 3 products seems to be the motive for the rebranding. Facebook opted to add their rebranded logo onto each of these social platforms to ensure clarity with ownership. 
Is it really going to help fix Facebook’s problems?
It’s fair to say, it hasn’t received the best response since it was announced but possibly we’ll start to see a difference in opinions.
Antonio Lucio, Facebook Chief Marketing Officer said that ‘the brand change is a better way to communicate our ownership structure to the people and businesses who use our service to connect, share, build community and grow their audiences’. To be fair, Facebook might (hopefully) be heading in the right direction with this rebranding.
However, some of the public undoubtedly still don’t want to put their trust into the social platform and I think it may take more than just a logo change to gain the public’s trust after one too many failures.
