The iTunes Store (introduced April 29, 2003) is an online media store run by Apple and accessed through iTunes. The store became the market leader soon after its launch and Apple announced the sale of videos through the store on October 12, 2005. Full-length movies became available on September 12, 2006.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): When were videos made available through the iTunes store?
