I've been a long time reader, but decided to start posting becuase I can't reconcile an issue on my own.  I am wondering if someone can explain to me how the PS3 has gone from 16.9% of the total console market WW to 17.3% of the total console market WW over the past 4  weeks.  As far as I can tell they have been pretty greatly outsold by both the Wii and the 360 during that time frame, so I am just wondering what I am missing, how are they gaining market share by selling less WW than their competitors?  Just curious for an analysis, not anything biased.  Thanks.

Dolla Dolla where are you to explain it again.

I shall try it to explain it.

If Person A sold 90 Oranges and Person B 10 oranges then it means that

Person A haves 90% of the Market Share and Person B 10%

One week later

Person A sold 60 Oranges and Person B 40 Oranges.

In total Person A sold 150 Oranges = 75% Of the market.

In total Person B sold 50 Oranges = 25% Of the Market


Got it?

Thanks, makes perfect sense now, I knew it was easier than what I was trying to think of.

Its marketshare will increase until its percentage of the weekly sales equals its percentage of lifetime sales. By the same token, the 360's marketshare will decrease until its percentage of weekly sales equals its percentage of lifetime sales.

Thank you teacher, that was one heck of an understandable explanation :D

If you have 3 products which are selling at the following rates:

100 PS3's per Week
300 XBox 360's per Week
600 Wii systems per Week

than (if given enough time at these rates) these systems should eventually have total marketshare of:

10% PS3
30% XBox 360
60% Wii

Now, being that the XBox 360 launched earlier than the other systems it started out with 100% marketshare ... As long as the PS3 and Wii's weekly marketshare is greater than their Total market share their total market share will improve, and as long as the XBox 360's weekly market share is less than its total marketshare its total market share will shrink.

A whole .2%, but is the start of the Sony Domination :P

Fixed.

Haha, nice fix FishyJoe (though, I think they would be lucky if it was only a 5 cent loss on each one )

 There was really no reason to fix it, it doesn't makes any sense now.

We are talking about marketing Share not about the profits of the losses.
