RAPLH LAUREN - OLD NAVY - DIOR

First brand I want to look at is RALPH LAUREN, we know that companies now are integrating social media activities and engagement as part of their overall marketing and PR strategy, but my focus is on the use of Videos and I have to say that on the Official Facebook page there aren't interesting pieces.
Additionally this is what we can find on the Youtube page.  

                                            Catwalks, advertising and backstages

Old navy is a popular clothing and accessories retailer owned by American multinational Corporation Gap Inc. <sup>(according to wikipedia)

So the brand is totally different from Ralph Lauren, the target is different, the product itself is different and also the communication. The last post on Fb wall consists in a hilarious video, taken from a commercial. There are lots of comments of users, so definitely with this movie they have found the way to create engagement.  You can watch it here: https://www.facebook.com/photo.php?v=10152076778117021&set=vb.20395377020&type=2&theater

^{And finally we can talk about Dior. Personally I love the french maison, I had to do a reaserch about the history of the maison and I was impressed by the strong connection between the couturier and art. Besides the fact that I am fascinated by this brand, let's highline its social media strategy!
It's interesting that the Facebook page has the photos and videos sections separate, and they're organized very well. There are different videos, from commercials to interviews, this is the last short movie about Dior cruise 2015 . "Watch the Dior Cruise 2015 show presented in New York.

Just because I'm very curious I've looked at the Twitter official page, but they share only many and many pictures. Not videos at all!
