Microsoft is airing its first national Super Bowl advert on Sunday. While the software giant has been busy backing the Seattle Seahawks, it has also found the time to create a series of empowering videos that mark a fresh marketing approach for the company. It’s easy to think of Microsoft as a corporate giant that has missed mobile and tablets, but the reality is that millions of people still rely on its vast array of software products for their daily work. That’s the message that Microsoft is trying to hammer home during the Super Bowl this year.
