Kimmel’s 2025 average viewership of 1.6 million is down 37% compared to 2015 totals.
The decline is even more significant among the advertiser-coveted demographic of adults, ages 25-54. "Jimmy Kimmel Live!" averaged nearly 1 million viewers in the critical demo in 2015 but plummeted to only 261,000 in 2025. The ABC late-night program shed a staggering 72% of the critical demo over the past decade.
