The main television coverage of Celebrity Big Brother was screened on CBS during the winter of the 2017--18 network television season. CBS decided to schedule the spin-off during the February 2018 sweeps period to counterprogram NBC's coverage of the 2018 Winter Olympics. Episodes aired on Sundays, Mondays, Wednesdays, and Fridays with two special episodes on Thursday, February 8 and Saturday, February 24. Most episodes aired for one hour and aired from 8:00-9:00 p.m. EST; the Friday episodes and the season finale, however, ran for two hours each (from 8:00-10:00 p.m. EST). The live Internet feeds returned for the American version of Celebrity Big Brother as part of CBS All Access. Alongside the weekly shows on CBS, the companion series Big Brother: After Dark returned on Pop under the title Celebrity Big Brother: After Dark. The show provided live coverage nightly from inside the House.
