HTML 4.0, now consisting of 92 elements, became the
"official" standard in April of '98.
This is the HTML 4.0 Transitional DTD, which includes
presentation attributes and elements that W3C expects to phase out
as support for style sheets matures. Authors should use the Strict
DTD when possible, but may use the Transitional DTD when support
for presentation attribute and elements is required.
HTML 4.0 includes mechanisms for style sheets, scripting,
embedding objects, improved support for right to left and mixed
direction text, and enhancements to forms for improved
accessibility for people with disabilities.

HTML 4.0 was a move back to the separation of structure
and presentation. Some of the tags that had been introduced
in HTML 3.2 were already being deprecated. Indeed, several
attributes were first introduced in HTML 4.0,
as already deprecated.
Some of these include the FACE
attribute for the FONT element,
the ALIGN attribute for nearly all elements
and the BGCOLOR, and BACKGROUND
attributes.
This kind of text-block highlighting is visible on all browsers
which support the bgcolor attribute of tables,
but the use of Style Sheets forces people who use older
browsers to either upgrade, or forego the presentation effects.
(which then renders the page much as HTML
2.0 did)

Modems had been upgraded to 33.6 and 56 kbps
(even some cable-modem and DSL in limited markets)
and the number of websites was exploding. Advertisers
found an almost unlimited supply of places to advertise,
so, as dictated by the law of supply and demand,
advertising rates plummetted.
A website could expect to reap $20 per thousand
impressions in 1997, but by 1999 that had dropped
90% to a mere $2 per thousand. Many of the dot-com
companies that had included advertising revenues in
their business plans could no longer support operations
in this new market. One would think such a development
would mean more sites forgoing irritating ads.
Unfortunately the dream of millions of ad hits generating
thousands of dollars keeps webmasters chasing the rainbow.
