Master Page updated , but changes are visible only for that Page(site) alone ?

Question

I updated v4.master in SharePoint designer to add a bread crum navigation control
 <div class="BreadCrumbWrap s4-notdlg"> 
       <asp:SiteMapPath runat="server" SiteMapProvider="SPContentMapProvider" id="ContentMap"   CssClass="BreadCrumbStyle" PathSeparator="&gt;"> 
       <CurrentNodeStyle CssClass="BreadCurrentNode" /> 
       <PathSeparatorStyle CssClass="BreadPathSeparator" />   
        </asp:SiteMapPath> 
      </div>
But the changes are visible only in that site. all other sites dont have bread crum control,
I added the bread crum in header section, and also in page layout section, but there is no change (bread crum navigation only visible in that site alone)
Why ?
I always thought master page edits will be visible in all sites of a site collection,
Am i going wrong some where (My site collection has about 30-35 sites, and new sites are created every now and then )
Please help

Answer 1

If the publishing features are turned on then the master pages for all the sites in the site collection are pulled from the master page gallery of the root site.  But if Publishing hasn't been enabled then each site uses the v4.master in its own master
page gallery.  It sounds like you haven't enabled the Publishing Infrastructure site collection feature and Publishing Site Feature in the root site of your site collection.
