You can't beat this kind of introduction to the story of a strategic business decision gone terribly wrong (via NY Times):
"Reed Hastings was soaking in a hot tub with a friend last month when he shared a secret: his company, Netflix, was about to announce a plan to divide its movie rental service into two — one offering streaming movies over the Internet, the other offering old-fashioned DVDs in the mail.
"'That is awful,' the friend, who was also a Netflix subscriber, told him under a starry sky in the Bay Area, according to Mr. Hastings. 'I don’t want to deal with two accounts.'
"Mr. Hastings ignored the warning, believing that chief executives should generally discount what their friends say."
