Yes, that's one way of doing it, although some fo the major
website hostings will slap a court order on you for breaching their trademarks or copyrights.
I have a few domains that consist of the popular name with the www in front (but no . ), such as wwwdomain.com - they get some traffic (obviously from those who suffer dyslexic fingers
)
At the end of the day, you have to be careful not to stir anyone into taking you to task over riding on the back their trademark names.
