For example if your YouTube Channel happens to provide valuable video content for a very specific audience. Say the channel teaches business owner how to organize their finances, track their expenses and save money on taxes. Any company who is trying to reach business owners would love to place their ads on that channel because you would both share the same demographic. The people who view that channel are their potential customers.
It's a little awkward, so we'll get straight to the point: This Sunday we humbly ask you to defend Wikipedia's independence. We depend on donations averaging about $16.36. But 98% of our readers in the U.S. are not responding to our messages, and time is running out to help in 2018. If everyone reading this gave $2.75, we could keep Wikipedia thriving for years to come. The price of your Sunday coffee is all we need. When we made Wikipedia a non-profit, people warned us we'd regret it. But if Wikipedia were commercial, it would be a great loss. Wikipedia unites all of us who love knowledge: contributors, readers and the donors who keep us thriving. The heart and soul of Wikipedia is a community of people working to bring you unlimited access to reliable information. Please take a minute to help us keep Wikipedia growing. Thank you.
