This second benchmarking report explores the degree to which the world’s top 50 online content-sharing services’ approaches to TVEC online have changed and evolved over the course of one year.
As the first benchmarking report did, this report provides an objective snapshot in time. It also informs efforts led by the OECD, in collaboration with member countries, businesses, civil society and academia, to develop a multi-stakeholder, consensusdriven framework and set of metrics for voluntary transparency reporting on TVEC online by content-sharing services.
The framework and metrics are intended to lead to a standardised template that any company wishing to report on TVEC can use, and that all OECD members can support.
Methodology
Social media platforms, video streaming Services and online communications services were identified based on their monthly average users (MAU). The MAU metric is commonly used by industry analysts and investors to determine a service’s popularity
and growth, and constitutes a reliable measure to rank with a fair degree of precision the relative size of services that thrive on user engagement.
Cloud-based file sharing Services were identified based on indicative market shares, a metric that is frequently used to determine the relevance of firms in a given industry segment. The third category includes a content management system and an online encyclopaedia.
The popularity of these two Services cannot be determined relative to the other two groups; however, their undoubted relevance warranted their inclusion. Their importance was determined on the basis of data (indicative market share and monthly pageviews) that reveal their reach and/or usage.
