The SX-70 film process owes its existence to Lady Bird Johnson, First Lady and wife of President Lyndon B. Lady Bird became aware of the trash in our National Parks created by the expended tabs of the original Polaroid film and requested that Polaroid Corporation invent a neater picture process. They did and the rest, as they say, is history. What you probably didn't know is that within a few years of its introduction it ranked Number One in dollar sales in drugstores, creating more cash flow than Kodak Instant Film or Kodacolor II film, which followed in order as numbers two and three. In Unit Sales it was number eight compared to number six for Kodacolor II, but significantly ahead of Kodak Instant Film which is not shown on the chart (it was number fourteen).
