By the end of last year the Xbox 360 was less than 200,000 units behind Wii in lifetime sales in the UK.
CVG also reported that data from GFK Chart-Track showed that there were four times more Microsoft consoles bought than Nintendo Wiis in 2012.
It added that the Nintendo DS was still the best selling device in lifetime sales in the UK, followed by the PlayStation 2, the Wii and then the Xbox 360.
It's good news for Microsoft, which recently saw a 29 per cent drop in revenue from the console, "due mainly to lower volumes of consoles sold and lower video game revenue."
Microsoft also reported that in its last quarter it shipped 5.9 million consoles in Q2 2013, compared with 8.2 million for the same period last year.
