Re "Where does all the PBS pledge money go?" Forum, March 18):
Simply put, the money goes to purchase programming from PBS and other programming services. Securing national programs is the most expensive part of our service, but offerings such as "Downton Abbey," "NOVA," "Frontline," "Sherlock," and educational children's programs such as "Sesame Street" and "Peg + Cat" are the returns on that investment.
Some pledge programs are seen more than once because of their popularity with viewers and their effectiveness at raising funds for our entire broadcast schedule.
