BB28 - Big Brother: Time Trip
Time Trip is official. The cast is not.
CBS made it official: BB28 is Big Brother: Time Trip, premiering Thursday, July 9 at 8/7c with a 90-minute episode. The theme, schedule, Unlocked panel, and a new fan vote are confirmed on the record. The cast, twist rules, and returnee question are not.

Confirmed
The BB28 receipts you can put on the calendar.
Confirmed means CBS, Paramount, or another primary source has put it on the record. Fan-site reports stay in the ledger until the official receipt lands.
Theme: Big Brother: Time Trip
Official as of July 1. Rooms, relics, and competitions move houseguests across time, with era-inspired powers built to disrupt strategy and alliances early. Every relic and era power is a potential power-map event, not set dressing.
Unlocked: panel and fan vote
Jerry O'Connell joins returning winners Taylor Hale and Derrick Levasseur when Unlocked returns Friday, July 10 at 8/7c. The premiere launches an interactive fan vote CBS says will have a major impact on the game.
The weekly rhythm
After premiere week: 90-minute Wednesdays, hour-long Thursdays with live evictions, and Sundays, plus scheduled Unlocked dates through late September. More broadcast hours mean more receipts to reconcile against the feeds.
Milestone: episode 1,000
BB28 makes Big Brother the first primetime series to reach 1,000 original episodes. That milestone is why the season leans on franchise history, and why every nostalgia beat should be read as a possible twist delivery mechanism.
Feeds on Paramount+ and Pluto TV
Live feeds remain available to Paramount+ subscribers and on Pluto TV. The exact switch-on time is still in reported-not-official territory. The feeds are where PocketBB's receipts come from, so that line matters here.
Pending
What we are not filling in yet.
This is where the preview earns trust: unknowns stay visible instead of getting padded into certainty. These items move only when there is a clear receipt.
Cast reveal: names, count, and whether the release language says all-new or includes alumni.
Official live-feed start time, currently reported as July 10 around 9 p.m. ET.
Fan-vote rules: what it awards, who is eligible, and how often it recurs.
Which episode is the 1,000th, and whether that milestone carries an in-game twist.
Twist specifics: how relics, era powers, and the time gimmick actually enter the game.
What gets tracked first
The first useful data will not be the cast photo. It will be the power map.
PocketBB is built around movement: who gets power, who becomes vulnerable, which social groups harden, and which receipts explain the shift later. Time Trip gives that map more moving parts before the first eviction even arrives.
First Head of Household result and whether week one creates a quick majority.
Alliance formation in the first 72 hours, when feeds usually reveal the real social map.
Any relic, era power, or Time Trip advantage, because each one is a power-map event.
Fan-vote mechanics once the July 10 Unlocked premiere publishes the rules.
Power-board changes, loud-day flags, and the receipts needed to explain the winner path later.
Receipt ledger
Time Trip moved from rumor to receipt. The rest stays sorted.
Official means CBS or Paramount on the record. Reported means credible, useful, and still waiting on a primary receipt. Rumor means interesting, not printable as fact.
Resolved: rumor to official
Time Trip theme
- Claim
- A time-travel or legacy-revisit season theme built around the 1,000th-episode milestone.
- Evidence
- Started as a translated advertiser-pitch leak in June. On July 1, CBS confirmed Big Brother: Time Trip by name in an official first-look release.
- Next receipt
- Confirmed July 1, 2026. The leak note stays up as the record of how this one traveled from rumor to receipt.
Reported, not official
Live-feed start time
- Claim
- Feeds begin Friday, July 10 around 9 p.m. ET, after the first Unlocked episode.
- Evidence
- A Pluto TV promo surfaced in the fan lane, with follow-up reporting from Big Brother outlets. Strong enough to track, not strong enough to print as official.
- Next receipt
- An official CBS, Paramount+, or Pluto TV announcement with the start time, or the feeds simply going live.
Rumor
Returning players
- Claim
- Some BB28 players or guests may be familiar faces.
- Evidence
- The official language, milestone framing, and theme all leave room for alumni, but CBS has not published cast names or roles.
- Next receipt
- The cast reveal, trailer, or premiere segment showing whether alumni are players, hosts, cameos, or twist obstacles.
Partially official
Fan-vote mechanics
- Claim
- Viewers get a vote with real impact on the game, launched through Unlocked on July 10.
- Evidence
- The vote's existence and major-impact framing are official. The rules, timing, eligibility, and exact prize are not.
- Next receipt
- Published voting rules or the on-air explanation July 10. Until then, PocketBB tracks it as a known unknown.
Premiere night, in your pocket
The house opens July 9. The power board opens with it.
When the feeds turn on, PocketBB turns into a live instrument: HOH and veto results, alliance movement, loud-day flags, and receipts you can scroll back through when someone claims they never said that.
