The strength of the Web isn't as a replacement for mass media. Its strength lies in numbers and obscurity. The Web is cool because you can find entertainment or information to suit any taste no matter how weird. Either use the Web to highlight and accentuate your mainstream offerings, or as a venue for your inventory of musty old material. Don't try to treat it as a substitute for TV or another mainstream medium.
Movies are a perfect example.
If the computer is your only source of entertainment, this is good news for you. The rest of us couldn't care less. We don't care because we've got better ways of watching movies. The video clips we watch on the computer are ones we can't get any other way, and we get them for free. The primary exception to this is pornography, but porn has always been unique in terms of what it can get away with online.
