The 2011 VIVA graphics package, designed in-house by MTV Networks Germany, is still my favorite look the channel ever had. I usually call it "mirror VIVA" because of the mirrored triangles used in the channel IDs and the song title straps.
The irony is that this design dropped right when VIVA was pivoting hard away from music to run reality shows. VIVA Poland adopted the same graphics on July 17, 2012, and while they eventually dropped the reality formats to bring back 24/7 music in 2015, the actual playlist was bleak. It was just an endless loop of EDM mixed with the exact same classics until the channel folded in October 2017.
Terrible programming eras aside, the design itself still works. If you watch those old idents today, the package completely holds up.
