Thank you very much.
I also want to ask about this with respect to the advertising campaigns. Largely, these have been PSAs about COVID. My understanding from your remarks today is that this new money is meant to continue those campaigns.
What techniques are you using to evaluate the success of those advertising dollars, to see if people are getting value for money with respect to those campaigns? You mentioned earlier that you've seen some success and you were taking credit for some of the awareness about social distancing measures and other things like that. How do you know that? What metrics do you use?
