As the economy grows and more businesses come into existence, there are fewer monopolies in the economy. A monopoly is where one company is in control of most of the market for that particular product. A modern-day example of a monopoly would be Google. Google is the primary way that people find information. Google also has many other platforms like drive, forms, sheets, slides, and Gmail. While there are other search engines such as Yahoo and Bing, Google is the preferred search engine that people use. Google dominates the market when it comes to search engines because of all of its diverse platforms spawned from the search engine. This allowed for Google to expand and take majority control of the market. While other search engine companies like Yahoo and Bing are used, they are used less by customers pushing them into a small margin of the economy. Google platforms are used in different schools and offices as the main source of communication. This helps to propel Google into a modern-day monopoly.
While I do have to agree with you, Google is a massive company. Although being a massive company doesn't mean it is a monopoly. Google as a search engine is preferred among a lot of people due to its larger index, and the that it finds what you are looking for faster than other search engines. Gmail is most popular because it is technically your Google Account. Youtube is big, but platforms such as Twitch are currently giving Youtube a run for its money. Google Drive/Google Docs are mainly used due to its convenience, and it still has competition such as Microsoft Word, DropBox, etc. Google as a phone company is nowhere near controlling the market, companies like Samsung and Apple control the majority and Google Pixels/Nexus only control a small number of phone users. Saying all this doesn't mean you are wrong or I am right. I just wanted to provide some information I have gathered.
