SIGNAL is an ongoing reality web-show following the members of tripleS in their everyday lives. Originally the series was filmed on and uploaded on the same day daily, however the show moved to a less frequent upload schedule during the Cream01 season to allow for pre-filmed content and a less rigorous schedule for the members and staff.
SIGNAL began airing on May 9, 2022 with the moving-in signal of the first member, Yoon SeoYeon. It currently has over 700 episodes, not including its spin off series, SIGNAL WEEKLY and SSSIGNAL, both of which have ended.
Release Schedule[]
From Monday to Friday, a SIGNAL episode is uploaded at 9:30PM KST. However, as of the Cream01 Arc, it was decided that the new episode schedule would be reorganized to Monday, Wednesday, and Friday, allowing the Content Team to edit episodes more comfortably and the members to film newer and more varied content.[1]
On Saturday, a SIGNAL WEEKLY episode, which featured a recap of the previous week with unseen footage, was uploaded at 9:30PM KST. On Sunday, a SSSIGNAL (SUNDAY SELFIE SIGNAL), a compilation of self filmed vlogs by the members taken the previous week, was uploaded at 9:30PM KST. By the end of 2023, both sub-series have ended as a result of SIGNAL's reorganization.
SIGNAL PICKED, a short clip from the episode of that day was uploaded on Twitter/X at 12:00PM KST.
Sub-series like Live SIGNAL mostly follow a release schedule, being announced on the first day of the week of its release. However, COSMO EXCLUSIVE SIGNAL does not follow a specific release schedule and are uploaded sporadically.
Series such as SecretBase and tripleS BEHIND are not connected to the SIGNAL series in name, however SecretBase does follow a release schedule, usually releasing at 9:30PM KST on Sundays, after SIGNAL WEEKLY episodes and before SSSIGNAL episodes. tripleS BEHIND does not follow any schedule.
