Regulation in this sector applies only to operators whose significant market power could prevent the full benefits of telecoms liberalisation from getting through to consumers. Wherever a market analysis has found tangible signs of sustainable competition, regulation has been trimmed back or removed altogether. However, much remains to be done. As of 30 September 2005, sixteen EU Member States had found no effective competition on one or more of the 18 electronic communications markets defined by the EU and had taken steps to boost competition on the markets concerned. Five Member States had found only partial competition on one or more of these markets and had imposed remedies where it was lacking. But nine Member States had yet to notify the Commission of their analyses of any of the 18 markets. Of the analysed markets (152 out of 450), 123 were not competitive, 19 fully competitive, and 10 partially competitive.
