Sofia's Diary was produced and created by Nuno Bernardo and Triona Campbell with their company beActive
Sofia's Diary is a drama that is shown online through the social networking site Bebo, which is the same site that hosts KateModern.
A version of Sofia's Diary originally came out in 2003 in Portugal. This means it actually predates the first video of lonelygirl15 which came out in 2006. Sofia is played by 22-year-old Rachel Hyde-Harvey.
Sofia's Diary was the second internet based show to make the transition to UK TV following its acquisition by Channel Five on April 17, 2008. The first two seasons of the show were broadcast on 'Fiver'.
Following an 8-month break, Sofia's Diary returned to Bebo to begin a 6-week third season, from May 29, 2009. This season differs to the first two, in that new episodes are only being shown on Tuesdays and Fridays, as opposed to every weekday.
Sure Girl originally sponsored Sofia's Diary. Season 3 of the show is being exclusively sponsored by Transport for London, to help increase awareness among teenagers of its road safety campaign.
