The Vampire Diaries is a drama series that premiered on The CW in 2009. The series, based loosely on the books written by L.J. Smith, focuses on the lives of the Salvatore brothers, who are played by Ian Somerhalder and Paul Wesley. The series began with a focus on the love triangle between the two brothers and Elena Gilbert, played by Nina Dobrev. However, the series has taken a number of twists and turns during the first six seasons. Fall 2015 saw the start of Season 7. Nina Dobrev left the series at the end of Season 6, so the series will shift its focus from the love triangle of Elena Gilbert to new areas. The series airs on Thursday nights.
