“I Love Lucy” pretty much created the television universe as we know it. Now it may be dated but it doesn’t get much more influential than that. The same could be said for Birth of a Nation for the motion picture industry. Very dated now but there is no denying it laid the foundation for the major Hollywood studios.
I love Lucy was the first multi-camera sitcom to be filmed before a live studio audience. CBS wouldn’t pay for the extra cameras so Desi made a deal and paid for the cameras and CBS signed over the rerun rights. Desi was a good businessman!
