NEW YORK (

TheStreet

) -- Video game sales jumped 4% in December, making it the biggest sales month ever for the sector.

According to the NPD Group, video game sales hit $5.53 billion during the month compared with $5.32 billion last year.

The sector was led up by sales of consoles, which surged 16%, offsetting the 7% decline in individual video games.

Nintendo's

Wii sold the most consoles -- 3.8 million.

Sony's

PlayStation 3 jumped nearly 90% to 1.36 million units, and

Microsoft's

Xbox 360 sold 1.31 million.

Still, a strong December couldn't completely negate a difficult 2009, as total revenues declined 8% to $19.66 billion from $21.4 billion in 2008.

Earlier this week

GameStop

(GME) - Get Report

announced that it is

repurchasing $300 million in stock

, which should boost the company's earnings per share by about 10%.

The news of the buyback came on the heels of disappointing holiday sales, which prompted the company to cut its fourth-quarter outlook.

Electronic Arts

(ERTS)

also announced on Monday that it was slashing its full-year forecast, citing weaker-than-expected sales during the holiday season. The company now expects a loss of $1.94 to $2.24 a share, from prior guidance of a loss between $1.20 and $2.05 a share.
