At that time, most television programs were broadcast live, and as the largest markets were in New York, the rest of the country received only images derived from kinescopes. Karl Freund, the cameraman on "I Love Lucy", and Arnaz himself have been credited with the development of the linked multifilm camera setup using adjacent sets in front of a live audience that became the standard production method for situation comedy. The use of film enabled every station around the country to broadcast high-quality images of the show. Arnaz was told it was impossible to allow an audience onto a sound stage, but he worked with Freund to design sets that accommodated audiences, allowed filming, and adhered to fire, health, and safety codes.
