Without connectivity, there can be no digital transformation of economies and societies. With this in mind, the OECD Recommendation of the Council on Broadband Development was adopted in 2004. Since then, broadband markets, underlying technologies, and the policies in place to spur the development of broadband networks have undergone significant changes. This document summarises the outcome of an extensive questionnaire sent to delegates of OECD countries and stakeholder groups. The questionnaire aimed to gather information on the experience of OECD countries concerning broadband development in general, and more particularly their experience in implementing the 2004 Recommendation. The responses to the questionnaire were used to inform the review and revision of the 2004 Recommendation, which resulted in the adoption of the 2021 OECD Council Recommendation on Broadband Connectivity.
