The online landscape is dominated by a handful of tech titans, with nine in 10 internet searches made through Google, 99 per cent of smartphones using Apple’s iOS and Google’s Android operating systems, and Facebook remaining the dominant social media platform.

Facebook has transformed the ways people communicate. Amazon pioneered online retailing and built internet skills which have enabled it to establish Amazon Web Services as a leader in cloud computing. As for Netflix, it has allowed people to watch movies at home whenever they want. And Google has put a wealth of knowledge at everyone’s fingertips. Each has made substantial…
