I run a gaming website so I would assume that my stats for people browsing on game consoles would be higher than most. Even so, for the last year:
- PlayStation 3 - 0.47%
- Nintendo Browser - 0.17%
- PlayStation Vita Browser - 0.13%
- Nintendo 3DS Browser - 0.06%
Not sure about Smart TVs, but for under 1% of my users, I don't think it's really a platform worth catering towards. These stats could vary site-to-site of course, but for a gaming site whose focused series has had entries on the PS3, the 3DS, and the PSP (so I would assume most of my users have at least one of them), it's an extremely miniscule amount of users.
