Introduction

WML (Wireless Markup Language) is the new web language for making sites on mobile phones.
Over the past few months new WAP (Wireless Applications Protocol) phones have become
extremely popular and many large websites have created special ‘mobile’ versions of their site.
Many people predict that, over the next few years, WAP sites will become even more popular
and e-commerce over mobile phones will be widely available.
The roots of WAP are rather interesting, as they are built on the premise of industry cooperation.
This is rather ironic, since the first official release of the protocol took place at the height of the
ill-remembered ‘Browser Wars’. It is undoubtedly this cooperation that was one of the major
propellants for the widespread acceptance of WAP, allowing the standard to be quickly developed
and integrated into the existing products of the many corporations responsible for its’
development. This open standard also led to the rise of many new start-ups focused upon
developing and marketing their own niche applications. Let’s turn towards a brief discussion of
this history, and how it ultimately led to the popularity seen today.
Way back when, in 1995, Ericcson spearheaded an effort to develop a general protocol that
would offer a variety of value added services to wireless networks.
