Comment on Should We Be Afraid of Apple, Google and Facebook? by John Conor
The US DoJ uses a particular test to determine if a firm has monopoly power - the Herfindahl - Hirschmann index (HHI). Using this as the sole indicator, and thinking reasonably carefully about the markets in which each plays (search and web-delivered ads for the first, 'social network' connections for the second): Google and Facebook absolutely have monopoly power. The answers for the others are less clear. I have not read Prof. Wu's book (and can't get it except, ahem, to my Kindle, since I live in Asia), so cannot tell if he used the DoJ numerical definition, or how precisely he used term monopoly at all.
