Background information and notes
CSI: Crime Scene Investigation is a popular television on CBS, originally running from 2000-2014. It was mentioned in Chapter 4 of 24 Declassified: Trinity. The previous chapter has a character watch Survivor, another CBS series. Both shows frequently aired back to back on Thursday nights. The first time Survivor was followed by "a repeat of CSI" was on April 15, 2001. (This creates a slight contradiction with the novel, which is supposed to take place in late 1999).
