How do I split a Large CSV file into Multiple CSV's Using Powershell

Question

I am a novice at powershell but this looks to be the best tool to do this task. have a csv file that looks like this:
Date,Policy,Application
10/13/2014,No,None
10/13/2014,No,None
10/13/2014,No,None
10/13/2014,No,None
10/13/2014,No,None
11/14/2013,Yes,AppBiz
11/14/2013,Yes,AppBiz
11/14/2013,Yes,AppBiz
07/04/2013,No,PeopleBiz
07/04/2013,No,PeopleBiz
07/04/2013,No,PeopleBiz
07/04/2013,No,PeopleBiz
Is it possible to split this CSV into multiple CSV's based on "Application".
Lets say the output might look like:
None.csv
10/13/2014,No,None
10/13/2014,No,None
10/13/2014,No,None
10/13/2014,No,None
10/13/2014,No,None
AppBiz.csv
11/14/2013,Yes,AppBiz
11/14/2013,Yes,AppBiz
11/14/2013,Yes,AppBiz
PeopleBiz.csv
07/04/2013,No,PeopleBiz
07/04/2013,No,PeopleBiz
07/04/2013,No,PeopleBiz
07/04/2013,No,PeopleBiz
Any help would be greatly appreciated

I think this might be what you want:
Import-Csv applications.csv |
Group Application |
foreach {
$_.Group | Export-Csv "$($_.Name).csv" -NoTypeInformation
[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "
Very nice! 4x faster..
I doubt the OP will get what you just did there..
