Mii March - AKA Mii Profile Picture Month - started life back in 2013 when a bunch of 3DS owners promoted their Miis in celebration of the console's second birthday. Since then, the movement - which involves changing your social media profile images to your Mii avatar - has grown in stature, and this year's event could be the biggest one yet.

That's because March will also see the launch of Nintendo's long-awaited Miitomo smartphone application, which is built around - your guessed it - Mii characters. The release of this app should drive interest in Miis, and encourage lapsed Nintendo fans to resurrect their character and give it some much-needed exposure.

When you consider that the Wii sold over 100 million units - significantly more than the 3DS and Wii U combined - that means there are a lot of Miis out there which have been unfairly ignored over the past few years. Mii March and Miitomo are the ideal excuse to dust these digital avatars off.

If you want to get involved, then you can join the movement by heading over to Facebook, Twitter, Instagram or Tumblr, and make sure you have a suitable Mii photo ready to use on those networks.
