Broadcast timeline and renewal pattern
Hawaii Five-0 followed an annual fall-to-spring cycle, with new seasons typically premiering in September and concluding in May. The show was renewed each year after strong live and DVR performance, which contributed to a decade-long run on CBS. Its move to a slightly later premiere in Season 5 (September 26) and adjustments in later seasons reflect scheduling refinements, but the overall pattern remained stable.
How Hawaii Five-0 compares in length
At 10 seasons and 240 episodes, Hawaii Five-0 ranks among long-running U.S. scripted series in its genre. For context:

- Hawaii Five-0: 10 seasons, 240 episodes (concluded)
- 24: 8 seasons, 192 episodes
- Lost: 6 seasons, 121 episodes
