For devotees of the Outback Steakhouse chain, a meal of horseradish-crusted filet mignon is seldom complete without the restaurant's signature offering — "the Bloomin' Onion" — a large, deep-fried onion, artfully sliced to resemble a flower in bloom.
"Last year, Outback partnered with Thuzi, to build an app that would offer a free Bloomin' Onion coupon to first 500,000 people to sign up as fans on the restaurant's Facebook page. Thuzi searched extensively for a solution that would meet all the needs of the viral campaign and found one in Windows Azure. When Thuzi launched the Facebook app in November last year, Outback's goal was to capture 500,000 fans in 30 days. It met that mark in just 18 days. While some Facebook users limited their activity to signing up as fans on the restaurant's page, the Bloomin' Onion campaign went truly viral when fans started to post links and invite their friends to sign up for the promotion," informs Microsoft.
