It really can depend on where you are. For example, in the US Google had a 4 percent marketshare in 2023. It actually doubled compared to 2022: that was 2 percent.
Buf if you happen to run with a group pf people who go against the grain and buy Pixels, it might very well feel like a dominant brand.
In our company for example, everyone has iPhones. So to me, they appear to have 100 percent marketshare, when reality is closer to 50-60 percent in most markets.
