To make matters even more impressive, the former Colbert Report host also surged past his Late Show predecessor David Letterman. Compared to the same night last year, Late Show spiked a massive 172 percent, and, compared the show's most recent premiere, it jumped 123 percent.
However, as for the conclusion of the last original Late Show, finales are also hard to compete with. Early figures for Letterman's May swan song gave the host a 9.3 rating among metered market households -- a stat that later translated into a two-decade high 13.76 million viewers.
