A Public Service Announcements (PSA) is often the most effective and cost efficient way to get our your message, serving the public good, to a broad audience.  TV stations are mandated by law to broadcast Public service messages -- so you are guaranteed a certain number of airings.  It is the most bang for your buck.  PSAs are an incredible way to get your message on the national airways on a budget.  Studio B Films produces and distributes professional 30-second spots to be aired as PSAs.
