据报道，该规定将由竞争和市场管理局(CMA)的一个专门部门执行，该局今年称需要新法规来约束科技巨头。英国竞争监管机构和CMA称，谷歌和Facebook在数字广告业务方面占据主导地位，在2019年总计140亿英镑(187亿美元)的广告支出中就占了80%左右。

It is reported that the regulation will be implemented by a specialized department of the competition and market authority (CMA), which this year said new rules are needed to restrain technology giants. Google and Facebook dominate the digital advertising business, accounting for about 80% of the total advertising spending of 14 billion pounds (18.7 billion dollars) in 2019, according to the UK competition regulator and CMA.
