Who accepts USDC?

Could you please elaborate on the question "Who accepts USDC?"? I'm curious to know which businesses, organizations, or individuals typically accept this form of cryptocurrency as payment. Are there specific types of merchants that are more likely to accept USDC? Also, are there any notable platforms or services that currently support USDC transactions? Additionally, I'm wondering if there are any geographical limitations or regions where USDC is more widely accepted? Understanding these aspects would help me gain a better perspective on the usage and acceptance of USDC in the cryptocurrency and finance world.
