<P> Metro ( officially known as Microsoft design language or MDL ) is a design language created by Microsoft . This design language is focused on typography and simplified icons , absence of clutter , increased content to ratio ( `` content before chrome '' ) , and basic geometric shapes . Early examples of Metro principles can be found in Encarta 95 and MSN 2.0 . The design language evolved in Windows Media Center and Zune and was formally introduced as `` Metro '' during the unveiling of Windows Phone 7 . It has since been incorporated into several of the company 's other products , including the Xbox 360 system software , Xbox One , Windows 8 , Windows Phone , and Outlook.com . Before the `` Microsoft design language '' title became official , Microsoft representative Qi Lu referred to it as the modern UI design language in his MIXX conference keynote speech . According to Microsoft , `` Metro '' has always been a codename and was never meant as a final product , but news websites attribute this change to trademark issues . </P>
