UPDATE: 11:25 AM: On its first night in its new time slot, Jimmy Kimmel Live had more viewers than The Late Show With David Letterman but fell short of topping The Tonight Show. ABC’s Kimmel pulled in 3.097 million viewers Tuesday night compared to 2.882 million for CBS’ Letterman and 3.274 million for Leno. The Tonight Show got 1.084 million in the Adults 18-49 demographic compared to Jimmy Kimmel Live’s 887,000. But Kimmel solidly bested The Late Show among demo, getting 30% more than Letterman’s 683,000.
PREVIOUSLY, 8:28 AM: Jimmy Kimmel had a very good night Tuesday. In his 11:35 PM debut for his ABC late-night talk show, the host beat now-rivals Jay Leno and David Letterman in households and in the key adults 18-49 demo. In 25 markets with local people meters, Jimmy Kimmel Live earned a 1.0/5 rating in 18-49, besting The Tonight Show’s 0.8/4 and Late Show’s 0.6/3. Among Nielsen’s 56 metered markets (with Memphis and Salt Lake City excluded), Kimmel’s move from midnight to a half-hour earlier saw his show receive a 2.8/8 household result, compared with Letterman’s 2.7/7 and Leno’s 2.4/6.
ABC announced in August that after a decade at midnight it was moving Kimmel to 11:35 PM . The ABC talk show hit solid highs last year with a debut visit from First Lady Michelle Obama in October and a first-time appearance by Kimmel’s hero Letterman on Halloween. At the end of October, Kimmel’s broadcast from Brooklyn during Hurricane Sandy ended up being the second-most-watched week in the show’s history. He also hosted the Primetime Emmys last year and was the headliner at the White House Correspondents Dinner in April. Jimmy Kimmel Live ended 2012 with its most-watched fourth quarter to date.
