KNTV NBC 11 plans to release a documentary it has produced on the 1906 earthquake on iTunes on Monday (April 10), a week before the program is scheduled to be broadcast on the station. MediaWeek says it’s the first time a San Francisco station has released a documentary through iTunes ahead of its air date. The documentary, “Echoes from the Past: The 1906 Earthquake,” will air on Channel 11 on April 18, the 100th anniversary of the historic quake. The nbc11.com web site will also have a timeline of the quake and a fictional diary depicting the quake through the eyes of a teenager.
