Stephen Colbert has ended his run on the Late Show, with the series finale featuring a musical send-off with Paul McCartney and a reunion of 'Strike Force Five'. The conclusion of Colbert's show has led to a shift in late-night television, with Jimmy Fallon directing viewers to Colbert's finale and other hosts, such as Jimmy Kimmel, potentially benefiting from the change. The outcome of this shift is unclear, with some reports indicating a ratings disaster for Colbert's replacement, while others suggest growth in viewership across the board.
