The real problem is actually the finality of the page. While people are
willing to scroll downwards they are not willing to scroll sideways. There
is a fixed width that has to be adhered to.

While it is perfectly possible to create a banner larger than 468 pixels
most sites have navigation bars on the side that consume 100 or so pixels.
Place the navigation bar by the banner and you are pretty close to the
maximum width of a 640 by 480 monitor. True, most monitors are bigger than
640 by 480 but most people do not browser with full size windows.

The problem is that html is an appaling layout control system. There is no
way of ensuring the layout of a page even with fixed image sizes, so
ensuring the layout of a page when the image sizes are changing is near
enough impossible.

In many ways MHEG (the Digital TV text format) is a more useful format, the
page size may be fixed and each page only contains little information but at
least I know how much space I have to fill, and hence how many lines of text
I can use. The best way to explain the difference is that MHEG is Quark
Xpress to HTML's Pagemaker. Both perform the same job and HTML is easier to
use but MHEG and eventually XML will provide the control Tom has always

(Of course American TV will not be using MHEG and Microsoft has only just
discovered Teletext so this is a mute point).
