For example, in the European Union, the development of broadband by building on pre-existing networks has determined the prevalence of DSL, while in the United States, pre-existing infrastructure has resulted in the dominance of cable (65 per cent of broadband connections).
例如，欧盟中通过开发已有网络发展宽带决定了DSL占优势，而美国已有的基础设施造成电缆占主导地位(占宽带连接的65%)。
