For Windows 8 or Windows Phone, Metro refers to the design language and overall style of the interface Microsoft is using for both its desktop/tablet and mobile operating systems.
Now, Metro is no longer a word Microsoft will be using to describe anything to do with their product line-up. It has officially been killed off as a term Microsoft’s staff and marketing is allowed to use.
The specific reason for this sudden change remains unclear. It was first thought to be due to a trademark infringement Microsoft couldn’t settle with German company Metro AG. Microsoft has since sent around an internal memo stating Metro will no longer be used following “discussions with an important European partner.”
It’s unlikely we’ll hear any further explanation beyond that officially, but we can expect to hear a replacement term and phrases coming out of Microsoft soon.
“We have used Metro style as a code name during the product development cycle across many of our product lines. As we get closer to launch and transition from industry dialog to a broad consumer dialog we will use our commercial names,” a Microsoft spokeswoman said in a statement .
Microsoft reportedly was notifying its developers not to use the word “Metro” within their apps and swap that term for “New User Interface.”
