Part 2: Key definitions Section 4: "Regulated service", "Part 3 service" etc
This section defines the term "regulated service" and other related terms used in the Act.
	Subsection (2) sets out when user-to-user services and search services will be regulated user-to-user services and regulated search services. To be regulated, such services must have links with the United Kingdom and not be exempt under Schedule 1 or Schedule 2. Subsection (3) states that these regulated user-to-user services and search services are referred to as Part 3 services in the Act.
	Subsection (4) defines "regulated service" as meaning a regulated user-to-user service, a regulated search service, or a service with links to the United Kingdom that publishes or displays provider pornographic content.
	Subsections (5) and (6) clarify the circumstances under which a user-to-user or search service has links with the United Kingdom. A service will be in scope if it has a significant number of users in the United Kingdom or if the United Kingdom is a target market. A service will also be in scope if it can be used in the United Kingdom by individuals and there are reasonable grounds to believe that there is a material risk of significant harm to individuals in the United Kingdom. Section 80(4) applies an equivalent test to internet services which publish or display provider pornographic content.
	As the regulatory framework established by the Act is focused on protecting individuals in the United Kingdom, these provisions ensure that services which do not have links to the United Kingdom are not in scope of regulation.
	Subsection (7) provides that a regulated user-to-user service that includes a public search engine (i.e. one which is not an internal business service) is referred to in the Act as a "combined service".
