Me and thousands of others.
Was one of the participants Joie Chen
No. Julie was not one of the participants. She is spoken for my CBS executive, Les Moonvest.
Was this on my local CBS affiliate, or some satellite feed?
This was broacast via internet web cam. Part of the CBS prime time show Big Brother 4, is the live 24/7 internet video feeds of the contestants. For more information, follow the article link to the CBS.COM web site.
Did CBS jam the ability to change the channel or turn off the tv?
No. Perverts like me were free to watch or not watch.
Did you videotape it for us?
No but I have seen some video and stills posted on BB4 fan web sites.
