Also with the DS selling more than 500,000 units over the month of December in the UK, Nintendo insisted that it was not only the biggest selling console over the Christmas period, but in the entire of the year 2006. The DS sold 1.7 million units across Europe in December.
"We have enjoyed one of the most successful Christmas holidays ever, with both Nintendo DS and Wii selling at staggering rates," said Nintendo Europe marketing director Laurent Fischer. "We are facing such high demand for both platforms that unfortunately we are facing stock shortages. However we are doing everything possible to combat this by attempting to deliver both consoles and games to retailers on a daily basis."
