Nielson shows a survey on the way consoles were used in 2011 and 2012 in US:

Game consoles aren’t just for gaming anymore. In fact, seventh-generation game consoles (e.g., PS3, Wii, Xbox 360) continue to gain traction as devices for watching video as well. For the third year in a row, Americans in 2012 spent more of their overall console time streaming video. According to recent data from Nielsen, the use of video-on-demand (VOD) and streaming services accounted for 22 percent of users’ overall time on these systems last year, up from 19 percent in 2011 and 13 percent in 2010.

PlayStation 3 users—who drove the trend in increased streaming activity—spent nearly 25 percent of their console time streaming content in 2012, up from 15 percent during the prior year. Wii users remained the most likely to spend their console time using VOD and streaming (32%), while Xbox 360 users spent about 13 percent of their usage time for VOD and streaming content, the same amount of time as last year.

Beyond video, users of seventh-gen consoles are also unique in how they use their multi-functional systems. In 2012, Xbox 360 users spent the most time (33%) gaming online, while Wii users spent the highest share of time (40%) playing games offline. DVD/Blu-ray use in gaming consoles is declining, given the rise in VOD and streaming, but PS3 users were still the most likely to spend time watching DVDs/Blu-rays (18%).

We will feature more insights on gamers, console dynamics and allocations of time and money within gaming and the broader entertainment category in our Nielsen webinar, U.S. Gaming: A 360° View, scheduled for Thursday, March 14. For information, click here.

Methodology

Survey of 2,500+ general population consumers (including game console users) in the U.S. conducted in October 2011 and October 2012.

According to this Xbox 360 users definitely spend a lot more time playing games than PS3-users but I will keep the rest of the data (and the comments regarding that the survey is wrong, etc.) up to you ;)

Nope, according to this Xbox 360 users spend a bigger fraction of the total time of usage of the console playing games. That's not necessarily more time.

For example: notice how the watching Blu-ray/DVD section is all skewed to the PS3 (obviosuly)? That extra 8-9% time of usage of the console might be what makes the very same absolute value of gaming time take a lesser percentage on PS3 than 360.

Or maybe not: you need absolute times to draw any conclusion.

It's not that the survey or the sampling is wrong. It's that you read it wrong.

Not necessarily wrong unless there are the total hours of usage. Respectively would also make my point clearer.

Fixed

So of each console's time:

• The average Xbox 360 gamer plays more online/offline games with their time than the PS3. Wii holds highest percentage of offline gaming which makes sense since their online is far less developed.
• The average PS3 owner watches more streaming and disc based content with their time than the 360 user. Wii again very strong in this regard. That's actually quite shocking since it lacks HD support for those streaming services. But at the same time it doesn't even register for disc based usage.

One thing I see with this. The fact that the 360 has a paid online service and with the more established/smoother online gameplay offerings of multiplats makes it the majority choice for online play. Yes, I understand this is not a total time comparison between consoles. It is telling though that of each console's respected usage, the 360 owners do more gaming than their PS3 owning counterparts on average.

PS3 very strong media usage since online service is free and includes blu-ray drive.

Wii very strong in offline gaming and streaming content, but very poor in online gaming, disc based media, and download based media.

This is a US based study, which is more dominated by online play and the 360. That would definitely explain the usage differences of 360 vs PS3 in the online/offline gaming areas.

It's not about being clearer: your claim

"According to this Xbox 360 users definitely spend a lot more time playing games than PS3-users..." (bold mine)

is a false implication, even if the thesis ends up being true.

Yes, you are right :) Sorry, next time I will spend more seconds to stuff like this :)

For what is worth, I actually expect absolute usage numbers to confirm your thesis. It's US after all, I expect a younger demographic for the 360 with more time on their hands.

For absolute numbers you should ask the source of this survey. But why do expect a younger demographic? Because it would fit better to usage-fractions? Perhaps based on a former survey?
