lonelygirl15 Season One Finale
The Season One Finale, otherwise known as 12 in 12, in the lonelygirl15 series took place on August 3rd, 2007. Starting at 8:00 AM Pacific Standard Time, one video was posted every hour, on the hour, for twelve hours on MySpaceTV. Fans were also able to participate with the characters in various ways, including chats and meeting locations.
Nikki Bower first appeared in the "HymnOfOne" unofficial IRC chat room following the first season finale video. At 2:16 PM she began talking to users logged in.

The columns of numbers in Nikki's picture add up to 111 (each) x3 columns = 333, so people think the meeting time at the statue is 3:33.
On Friday, August 3, 2007, we will have our Season Finale of Season One of Lonelygirl15. It’s what you all have been asking for, and a reason why we have been so busy. We will upload 12 episodes, one per hour, over the course of 12 consecutive hours. Also, comprehensive catch-up video will be available online two days prior to the Season Finale Event.
So grab your popcorn, tell five of your friends, and join us for this day long event! Oh yeah, Season 2 starts the following Monday [August 6th, 2007].
They later posted a follow up, clarifying that the event would be starting at 8 am PST. 
The suggestion of "24 Videos in 24 Hours" was first posted in comment 230 of the Is He Out There? video on the in March 2007, as documented on the Breeniversisms page. The announcement includes both of the key ideas presented in the original suggestion: a concept of a special "season ending" event, and the rapid release of a hourly videos in a single day. The original idea was further developed by fans in a discussion thread on the forums, "24 in 24: How can it be done?"
- The first six videos of the season finale were erroneously uploaded to MySpaceTV and viewable at 6:30 PM on August 2nd, 2007. The creators quickly noted the error and asked for anyone that had seen the videos to not spoil the plot for everyone else. The videos were pulled down shortly after.
