Search engine results account for 90% of the internet data ever collected. Now, you can fathom the important role Google and Microsoft ecosystems play in the whole data collection research work.
The second top source would be Mobile data and telecom companies. These services work with data science communities to source data of various types and share these based on a company’s data science requirements.
GPS, Bluetooth, and Wi-fi
