Where Do Social Network Sites Fit in ISIC Rev. 5 Content Distribution?

Social network sites and content distribution in ISIC Rev. 5, UN Statistics Division, raise a question that older classifications handled less clearly: a site that hosts, organises and distributes content created by users or partners is not simply a telephone network and not simply a publisher of its own titles. In ISIC Rev. 5 the content distribution side of such a site is described within the publishing, broadcasting and content area, while pure transmission and computing infrastructure sit in Section K. The exact placement depends on what the site mainly does, as described in the UNSD structure.

A platform that is neither a telephone network nor a traditional publisher

Social network sites pose a classification puzzle because they do two things at once, and neither half alone describes them. They host, organise, and distribute content created by users or partners, and they do so at a scale that makes them a major route by which the public encounters news, entertainment, and everyday life. That distribution work is not simply a telephone network, because a network carries signals without organising them into feeds or recommending them to viewers. It is not simply publishing either, because the site does not create most of the content it carries and does not issue it as its own titles.

Short videos, feeds, and the work of organising attention

Imagine a site where users post short videos, and follow the site’s own work step by step. The site receives the videos, organises them into feeds, recommends them to other users, and shows them in an order shaped by its own presentation rules. The users created the videos, but the site did the distributing: it chose the arrangement, it surfaced some videos and not others, and it presented the result as a continuous service to its audience. That organising and presenting work is the content distribution activity described here, and it includes curating, organising, and presenting content feeds, distributing user created and partner content through the site, and related content distribution services described in the UNSD entry for this area.

Set beside that site a different company that only rents server space to it, without organising or distributing the videos. That company provides computing infrastructure, and it would be described in Section K of ISIC Rev. 5, UN Statistics Division. The contrast is instructive because the two companies are technically entangled: without servers the site cannot run, and without the site the servers have nothing to carry. Statistically, though, they do different jobs, and the classification separates the job of distributing content from the job of providing the machines it runs on.

Four neighbours, each testing a different edge

Internet access provision in Section K tests the transmission edge: a provider that gives users a connection, without organising content into feeds, is not distributing content in the sense used here. Custom software development in Section K tests the building edge: a company that develops software for a client as a programming service is building a tool, not operating a distribution service. Own title publishing tests the creation edge: a site operator whose main activity is publishing its own newspaper or magazine is issuing its own titles, and that issuing work is publishing, not platform distribution. Data hosting without content distribution tests the storage edge: hosting data for clients, without presenting it to an audience as organised content, is infrastructure, not distribution.

Why this boundary matters for how public attention is counted

Social platforms now carry a large share of public attention, advertising, and news consumption. Counting them only as technology companies would hide their role as content distributors, and a reader of the statistics would miss one of the main routes by which content now reaches people. Counting every platform as a publisher would make the opposite error, ignoring the fact that they do not create most of the content they carry, and inflating the publishing total with distribution work.

Reading a platform case without guessing

Locate this activity in the UNSD structure, note the exact wording at each level, and compare it with the Section K entries for access, programming, and hosting, and with the publishing entry for own titles. Pay particular attention to whether the activity described matches the entry in full, including any exclusions noted there, and to what the site mainly does when its technical, publishing, and distribution work are weighed together. Confirm the result with the national statistical institute or business register before it is used in a return or a register.

This guide is statistical classification only, and it does not determine any reader’s code, principal activity, or registration. The national statistical institute or business register that holds the record is the place to confirm a real platform case, with the full UNSD wording for that case in hand.
