1. Summary of the results

The analyses provided suggest that Jimmy Kimmel Live! has the highest ratings among the 18-49 demographic, with 220,000 viewers, narrowly edging out The Late Show with Stephen Colbert with 219,000 viewers [1]. However, it's worth noting that Gutfeld! has the highest overall ratings with 238,000 viewers in the demo, according to one source [2]. The Tonight Show Starring Jimmy Fallon had significantly lower ratings, with 157,000 viewers in the 18-49 demographic [1]. The sources also report a decline in late-night TV viewership and advertising revenue [3] [4] [2], which may impact the ratings of these shows. Additionally, clip watchers skew younger, with 7 in 10 Americans under 30 watching clips from late-night TV shows [5].

2. Missing context/alternative viewpoints

Some sources do not provide specific information on the current late-night show ratings among the 18-49 demographic [3] [4], which limits the understanding of the topic. Furthermore, the demographic breakdown of viewers for each show is not consistently reported [1], making it difficult to compare the shows directly. The sources also do not account for the impact of streaming services on traditional TV viewership [3] [4] [2], which could be a significant factor in the decline of late-night TV viewership. Democrats are more likely to watch late-night talk shows, according to one source [5], which may influence the ratings of certain shows. The time slot and scheduling of each show may also affect their ratings, but this information is not provided in the analyses [3] [1].

3. Potential misinformation/bias in the original statement

The original statement asks which late-night show has the highest ratings among the 18-49 demographic, but does not consider other important factors such as overall viewership or streaming numbers [3] [4] [2]. The sources provided may have different methodologies for collecting ratings data, which could lead to inconsistencies in the reported numbers [1]. Jimmy Kimmel Live! and The Late Show with Stephen Colbert may benefit from the framing of the original statement, as they are the primary focus of the analyses [1]. On the other hand, The Tonight Show Starring Jimmy Fallon and Gutfeld! may be at a disadvantage, as their ratings are not as prominently featured in the analyses [3] [2] [1]. The sources may also have political biases, as one source notes that Democrats are more likely to watch late-night talk shows [5], which could influence the reporting of ratings data [3] [4] [2].
