'US, ' : ''); June 4, 2008 - A study recently conducted by consumer research group Nielsen found that younger gamers spend most of their time playing the Xbox 360, and older gamers while away the hours with the PlayStation 3. In both age groups, the Wii came in a distant second in total amount of play time received.

Conducted April 2007 to February 2008, gamers ages 10 to 26 spent almost 63 percent of their gaming time playing the Xbox 360. The same age group spent a quarter of their time playing the Wii and only 12 percent playing the PlayStation 3. The average number of play sessions per day were about equal for each console: 2.20 for the 360, 2.12 for the PS3, and 2.07 for the Wii. On the 360 and PS3, each play session lasted about 73 minutes. The reason for the discrepancy in total play times for these systems is because gamers played their 360 almost 28 days a month while the PS3 was only turned on 21 days a month. The Wii was played 19.66 days a month and each play session lasted about 53 minutes.

Looking at gamers over 26 years old, the 360 and PS3 switch places and leave the Wii in the middle ground. The PS3 took up almost 52 percent of gamers' time; the Wii 28 percent; the 360 almost 20 percent. Older Wii gamers played fewer sessions in a day: 1.80. Even though this age range spent much less time playing the 360 than the PS3, they played more 360 sessions each day -- 2.57, as compared to 2.20 on the PS3. The length of an average play session was shorter for each console in this age group: 55 minutes on PS3, 52 on 360, and 47 on Wii. These gamers also only turned their Wiis on 12 days a month, as compared to almost 22 days for the 360 and 19 for the PS3.

 EDIT:The Nelson group recently stated that they made a mistake with the table and that the Xbox 360 and PS3 for the 27+ demographic should be swapped (the PS3 getting less than 20% usage).

This is my response to this topic:

Out of 100% that is how much I play the following systems.

The Xbox 360 is used more because of its diverse line-up.
The Wii is used when I'm with my family and its somewhat line-up
The Playstation 3 gets use very little considering I am playing some PS2 and PS1 games on it, not that many PS3 games.

The Nintendo DS and PSP are only used when I'm at home about to fall asleep or somewhere boring.

Well in my circle of friends it's something like this:

Xbox360: 15%

PS3: 15%

Wii: 70 %

we are all around 24 - 29 years

For me It's wii 50%, PC 30%, 360 5%, and Ps3 15%.

OH that is only counting this gen systems.With other consoles. Snes 30% Ds 25% Psp 5% Ps2 20% Wii 15% Pc about 10 % ps3 and 360 probably like a fraction of a percent.  Other consolesare less than ps360 right now so I won't add them.

I use my wii 100% of the time

umm..

PS3: 80%
GC: 10%
PC: 10%

is the break down of my gaming sessions

I only have the Wii so it's 100% for me.

PC: 50%
PS3: 50%
PSP: 0%

PC : 35% ( Wow exclusively).
PS3 : 65%

would be about right for me

For a while it has been :
Wii : 100% (Brawl, Kart, Wii Fit, Boom Blox, a bit of Galaxy too)

Before, it was around :

Wii : 80%
PS2 : 10 % (Guitar Hero mostly)
PC : 10% (Starcraft and Diablo II:LOD)
