Encuentro is an educational TV channel operated by the government of Argentina. Earlier this month, the channel launched a new look with a new logo.
Apparently starting with the old logo, the new one is extended and with a more three-dimensional look. The graphics package extends the isometric look further with different visuals in bright colours.
The old logo was created by Steinbranding; there doesn't seem to be a design credit for the new one available at the moment. It was revealed in October and launched on November 7.
