The Nintendo Wii browser uses the TV media type if it is there otherwise uses the Screen media type. It works better than handheld as there is no, or less legacy content out there using TV which would break modern browsers. 

I believe the TV media type is quite useful as modern TVs have pretty big resolution now (so you can;t do the trick like with mobile for applying style when the resolution is lower), but you want a somewhat different experience on TV. You generally sit close to a desktop or laptop so can have regular size text, while on TV you are usually sitting back on the couch, so want to pump up the text size for example. Using a TV media type makes it much easier to detect the user is on a TV, providing browser vendors support it. TVs also come in a standard set of resolutions (1080p/i 720, SD etc) so the TV media type in combination with media queries for those resolutions can be quite powerful if supported.
