I think economists are still happy to use the current term. The Herfinadahl-Hirschman Index is a widely used measure of market concentration. It's calculated completely independently of how the firms in the market go about getting and protecting their market share. If the HHI is high enough, and depending on how important the market is, this can be a sign that the market should be investigated to ensure that there aren't monopolistic anti-competitive or anti-consumer practices taking place. Google is by far the biggest player in the search market (outside China at least), so I don't think an investigation is unjustified. There have been more than enough posts on HN and elsewhere about decisions Google have made over the years that show disregard for both competitors (not so much in search, but in other areas where Google has a footprint) and consumers. https://en.wikipedia.org/wiki/Herfindahl%E2%80%93Hirschman_Index https://en.wikipedia.org/wiki/Herfindahl%E2%80%93Hirschman_I...
