You didn't ask the next question, which is: 

Why is it a shell built-in?  Why isn't it a stand alone utility? 

The answer goes into a bit of the Zen of UNIX, so I'll reply with 
(what I hope) is a Zen answer: 

 $ cat cd.sh 
#!/bin/sh 
cd $1 
 $ pwd 
/home/bene/tmp 
 $ ./cd.sh /etc 
 $ pwd 
/home/bene/tmp 

Why didn't the directory change?
