side Geneva, Switzerland) and cooperating universities worldwide. Within a few
years, the WWW became the de facto standard for information
posting and brows-
ing on the Internet.
The layout and content of the digital good or service itself is not usually subject
to standards: there is no standard concerning the content and presentation of, for
example, Facebook, Twitter, Netflix, and Apple and Android apps.
To reach the
market, they must only support the standards required for accessing the Internet
and for interactions with the users (the World Wide Web standards).
Definition 15.1 Standards
A
de jure standard is
obligatory, for example, the use of the radio spectrum as defined
in the Radio Regulations of the ITU.
A de facto
standard is
a convention, procedure, or technology developed by the
users of the standard (e.g., the 5G standard of 3GPP) or been selected by market
forces (e.g., VHS as the standard for videocassette recorders). The de facto standard
is not obligatory. A de facto standard
is often referred to as industry standard.
An
open standard is a publicly available standard (e.g., the standards of ETSI,
ITU, and 3GPP). The standard may be free of charge or be
subject to a usage fee or
a patent licensing fee. Most de facto standards are open standards.

Standards Organizations
There are several organizations and groups specifying and standardizing ICT
infrastructures, protocols, and operations.
In this section, we will just look at some
of the organizations and groups having the biggest impact on the evolution of the
technologies and services supported by ICT. Some of them are based on interna-
tional charters (ITU, ETSI, and 3GPP), while others are
nonprofit interest groups
dedicated to a particular field of standardization (the Internet Society and the
World Wide Web Consortium). The standards produced by these organizations
and groups are open-source standards, meaning that
anyone may load down and
apply the standards free of charge. However, buying open-source standards from
ITU and ETSI are often subject to certain fees.
