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?
