The Dharma Initiative
In 2001, after Stuart Radzinsky's alleged suicide in The Swan, Kelvin Inman, a man who found Desmond adrift on the beach, was still working for the Dharma Initiative in the Swan station.
Lost producer Carlton Cuse confirms in a podcast that Kelvin was indeed a member of the Dharma Initiative.
In the "Lost Experience", an actor portraying fictional Hanso Foundation executive Hugh McIntyre appeared on Jimmy Kimmel Live, where he stated that the Foundation had stopped funding the Dharma Initiative in 1987.
However, in season 2, an air drop of supplies arrived for the Swan station. As an airdrop would require a cargo plane, pilots, parachutes, a loadmaster, and the supplies themselves, this would suggest someone is still providing funding for its activities.
The Lost series uses pop culture songs sparingly, and used a mainly orchestral score (consisting usually of divided Strings, Percussion, Harp and 3 Trombones.)
These elements include frequent appearances of black and white, which reflect the dualism within characters and situations; as well as rebellion in almost all characters, especially Kate; dysfunctional family situations (especially ones that revolve around the fathers of many characters), as portrayed in the lives of nearly all the main characters; apocalyptic references, including Desmond's pushing the button to forestall the end of the world; coincidence versus fate, revealed most apparently through the juxtaposition of the characters Locke and Mr. Eko; conflict between science and faith, embodied by the leadership tug-of-war between Jack and Locke.
