Seems like almost every company has shifted to a more touching tone in the way they market their products. This, I guess, has come from the idea that advertisements should not be ads, rather they should be ideas and emotions. They should not focus on what your product is, rather it should focus on why your product matters.
We have seen this with the new McDonalds ad, the new Budweiser ad, and now this Microsoft ad. This is not a secret considering that emotions make people share your message a lot more. They connect with the emotion of your message rather than the message itself. This is just the latest of ads to go viral because of it.
