Very large online platforms and very large online search engines may cause societal risks, different in scope and impact from those caused by smaller platforms. Providers of such very large online platforms and of very large online search engines should therefore bear the highest standard of due diligence obligations, proportionate to their societal impact. Once the number of active recipients of an online platform or of active recipients of an online search engine, calculated as an average over a period of six months, reaches a significant share of the Union population, the systemic risks the online platform or online search engine poses may have a disproportionate impact in the Union. Such significant reach should be considered to exist where such number exceeds an operational threshold set at 45 million, that is, a number equivalent to 10 % of the Union population. This operational threshold should be kept up to date and therefore the Commission should be empowered to supplement the provisions of this Regulation by adopting delegated acts, where necessary.
