Nielsen Media Research did some research on the age groups of the people that own gaming consoles. This is how it breaks down:

• PS3 has the oldest gamerbase, with the highest usage from the 18-24 age group.

Gamers who owned one or both of these consoles in their youth may have ‘graduated’ to the PS3 in their assumed adulthood.

• Xbox 360 attracts a slightly younger base, with more male gamers falling in the 12-17 age group.
• Wii is popular in boys age 6-11, and women age 25-34.

Does that seem correct to you? The PS3 age group seems accurate with the people that I know that have them. The 360 about right, but I do know some older people that have 360’s. The Wii is mixed as well. But most of the people I know that have Wii’s fit into that group. But my wife hates the idea the Wii, lol.
