Happy ‘World CSI Day’!

As CSI Files previously reported, today is “World CSI Day”. CBS is celebrating 15 years of the CSI franchise, along with tonight’s premiere of the latest spinoff, CSI: Cyber. In less than 15 minutes, CBS will attempt to break the Guinness World Record for “Largest Ever TV Drama Simulcast” by airing Cyber’s backdoor pilot, “Kitty”, in more than 150 countries at 7:00pm EST.
