Direct Answer: David Letterman on ABC
Jimmy Kimmel replaced David Letterman as the host of the nightly talk show on ABC in August 2003. Letterman had moved from NBC to ABC earlier that year, taking over the 11:35 PM ET/PT slot after the long run of Nightline. Kimmel’s Jimmy Kimmel Live! premiered immediately following Letterman’s Everybody Loves Raymond-adjacent setup, reshaping the late‑night landscape on the network. This shift was part of a broader industry realignment that also involved changes at NBC and CBS.
Late‑Night TV Landscape in 2003
To understand Kimmel’s arrival on ABC, it helps to look at the late‑night structure in place at the start of the 2003–2004 season:
- NBC: The Tonight Show with Jay Leno (11:35 PM ET/PT) following Late Night with Conan O’Brien.
- ABC: Letterman newly installed at 11:35 PM ET/PT after moving from CBS, with Kimmel’s show set to debut in the same slot later that fall.
- CBS: No national late‑night talk show, leaving room for affiliates and syndicated fare.
Kimmel’s move effectively supplanted Letterman on ABC, making him the third major network late‑night host to debut in that premiere season window.
Schedule Snapshots: 2002 vs. 2003
| Network | Late‑Night Lineup (2002–2003) | Late‑Night Lineup (2003–2004) |
|---|---|---|
| NBC | Leno (11:35 PM); O’Brien (12:35 AM) | Leno (11:35 PM); O’Brien (12:35 AM) |
| ABC | Letterman (11:35 PM) | Kimmel (11:35 PM) |
| CBS | No network talk show | No network talk show |
Format and Tone: Kimmel vs. Letterman
While both hosts occupy the same late‑night slot, their shows diverge in emphasis. Letterman’s ABC incarnation retained a more traditional monologue‑heavy, Top‑10 driven approach, whereas Kimmel leaned into rapid‑fire pop‑culture jokes, recurring bits, and celebrity interviews with a more casual, sometimes roving feel. The difference is partly a product of eras and audience expectations, but it also reflects each host’s comedic voice. Kimmel’s opening sequence, street‑style bits like Lie Witness News, and occasional political sketches distinguish his show from the tighter, more desk‑oriented pacing Letterman favored.
Notable Segments and Running Bits
- Lie Witness News: Hidden‑camera interviews where passersby invent answers to fabricated news stories.
- Mean Tweets: Reading aloud cruel (but often funny) tweets about celebrities.
- Historical Pranks: Office and on‑stage stunts that blur between harmless jokes and audience reactions.
Network Strategy and Affiliate Implications
From a network perspective, swapping Letterman for Kimmel was about cost, control, and demographic appeal. ABC sought a younger‑skewing, heavily promoted launch tied to Kimmel’s existing late‑night credibility after years at Nightline. For affiliates, the change altered cleared time, commercial load, and local promotional duties. Crucially, the Jimmy Kimmel Live! contract committed to a longer‑term showrun, which provided stability compared with the more transient arrangement many had expected for Letterman’s show. Ratings in the first season were respectable, enough to secure the timeslot and justify the investment.

Competitive Landscape and Viewer Impact
Kimmel’s debut on ABC intensified competition in the 11:35 PM slot, already crowded with Nightline and late local news. The broader talk‑show ecosystem remained three-network, though syndicated and cable options grew. Viewer choice expanded through digital clips and social conversation, with Kimmel’s team leaning into shareable moments. Kimmel’s focus on topicality and pop culture fit a younger audience more attuned to internet culture than the earlier Letterman-era viewer base, while retaining older viewers through familiar interview formats. Over time, the show has balanced broad appeal with niche segments, helping it remain a consistent late‑night presence.
Legacy and Lasting Influence
Replacing Letterman on ABC was a pivotal career moment for Kimmel, consolidating his shift from news correspondent to full‑time talk host. It also marked the beginning of a consolidated late‑night lineup that remains in place more than two decades later, with only incremental changes to the 11:35 PM block. Even as newer voices experiment with streaming and hybrid formats, Kimmel’s tenure since 2003 underscores how a single timeslot transition can reshape a network’s entertainment identity. The move continues to inform network decisions around host selection, contract structures, and audience targeting in late‑night television.
