Change SharePoint Title

When we need to change the SharePoint Title from the Site collection,
We can use PowerShell Command.

PS C:\Users\Administrator> $app = Get-SPWebApplication -Identity http://spsvr:1111

PS C:\Users\Administrator> $app.SuiteBarBrandingElementHtml = "<div class='ms-core-brandingText'></div>"
PS C:\Users\Administrator> $app.Update()
PS C:\Users\Administrator>

Now can see the Chaned TEXT. If we don't want anything we can set "EMPTY".
