No, the episodes aired at 11pm for the first few weeks - it was these episodes which got the show moved to 10pm.
Yeah, for the first series you had episodes at 11pm on Tuesdays to Thursdays, the Friday eviction and another show at 8pm on Mondays which would have the psychiatrists on it. As you say, it was moved to 10pm during that run.
In the second series - the best series - they had a show on Saturdays called Big Brother Reveals More, which I used to really enjoy, it featured some things they hadn't had time to show on the daily programmes so it was often the sillier and more whimsical bits, and it would end with the eviction from the housemates' perspective. One of the downsides of having more daily episodes is that you lost the more reflective, low key stuff like that. I remember series two was brought forward to launch on the Saturday right at the last minute, in the Radio Times they made reference throughout to it launching on the Monday and then when you got to the listings pages it was on the Saturday - the reason being Survivor was launching on the Monday.
Strange to think I can pinpoint events in my life by those early Big Brother series.
Weirdly I liked series 4, its probably the most gentle of all the series and did give us Jon Tickle!
Series 5 ramped it up, fight night, Nadia winning. I remember going to the pub the night of Nadias win and being the talk that night.
I think i gave up after series 7 when it got really daft!
I really liked series four, I liked Big Brother when everyone was nice and got on with each other, I know you can say it was boring but I like boring programmes. And as you say, Jon Tickle was the best housemate of all.
The exact moment I gave up on it was the fight in Series 5, specifically because on the next live show on the Friday, Davina just introduced the show by saying something like "Ooh, it all kicked off in the house this week!" and laughed it off, and I didn't like that at all because it was a really unpleasant moment that made for unsettling viewing and I don't think they ever really apologised to viewers who were upset or covered it with the seriousness it deserved.
It's the sort of cake-and-eat-it approach that was to eventually lead to the racism stuff, Channel Four pretending they had nothing to do with it and whatever went on in the house was entirely up to the housemates and they were just dutifully and impartially reporting it. Despite the fact that if the programme didn't exist, it wouldn't be happening.
