Since yesterday, December 1, Boomerang got a holiday look. Up next bumpers are changed, with snow, ice and music has that Christmas sound. Also the bumpers before the show start are adjusted and include holiday winter motives!! It looks really great and I'm happy Boomerang is paying attention to seasons and holidays now unlike in the past with the previous look which never changed. Here are some videos from Poland, Germany, Italy, France and Scandinavian countries. The look is basically the same for all of Europe with some tweaks in some countries.
EDIT: On Friday, December 14 they introduced a Christmas logo with snow, looks great. Here's a pic I took with my phone.
