Predating ann arbor
In the Sri Lanka video, Thomas Mittelwerk stated that "we all know what happened: the DHARMA Initiative failed." The date of DHARMA's collapse is unclear as well.In 2010, Benjamin Linus states that the DHARMA Initiative has not existed "for over twenty years".Off the Island, the DHARMA Initiative's activities were coordinated from Ann Arbor in Michigan.Not long after settling on the Island, the DHARMA Initiative fought an armed conflict with a group they called the Hostiles prior to 1973.According to Eloise Hawking, an unspecified man used The Lamp Post station in Los Angeles to find the location of the Island in the 1960s.Located underneath a church, the Lamp Post harnessed the unique pocket of energy in that area and used it to find other similar pockets around the globe.It was financially backed by Danish industrialist and munitions magnate Alvar Hanso and his Hanso Foundation.However, since The Lamp Post was built in the 1960s, the date of 1970 given by Pierre Chang in the orientation films may be incorrect.
After the slaughter, some of the DHARMA projects on the Island collapsed.
The DHARMA Initiative collapsed or was destroyed off the Island as well, although the details of this remain unclear.
In the Official Lost Podcasts, executive producers Damon Lindelof and Carlton Cuse also make frequent references to DHARMA's fall as a "collapse".
Hugh Mc Intyre of the Hanso Foundation said in an interview as part of The Lost Experience that the DHARMA Initiative's funding was cut in 1987.
However, this seems to conflict with the 1992 date for the Purge (if we are to take the math of Horace Goodspeed's spirit literally).
