Katie Couric's last day on NBC's Today show was the most Tivo'd broadcast of 2006, the digital video recorder company said Thursday. TiVo issued a list of the top-ten moments of the year, which also included: 2: Mel Gibson's interview with Good Morning America's Diane Sawyer about his DWI arrest; 3 Oprah's humiliation of writer James Frey, in which she accused him of betraying readers; 4. The characters Sara and Grissom becoming "a couple" on CSI; 5. Faith Hill's reaction to Carrie Underwood's win at the CMA Awards. In a statement, TiVo commented, "This is one of the many reasons why TiVo DVRs are a must-have for TV viewers and sports fans across the country, who can count on never missing those key moments or the big plays."
