Another example of the Osborne effect took place as a result of Nokia CEO Stephen Elop's implementation of the plan to shift away from Symbian to Windows Phone for its mobile software platform. On top of this, criticism of existing products was compared to the Ratner effect. Although it was known for some time that Nokia's Symbian phones were no longer competitive against iOS and Android, they still generated significant profit thanks to Nokia's brand recognition until Elop's announcement "effectively transformed the Symbian cash-cow into a dead duck". At the same time, Nokia's first Windows Phone devices would not be ready for a year, and once they were released their sales were not enough to replace the volume and profit of Symbian devices. Furthermore, the announcement that Windows Phone 7 devices would not be able to upgrade to Windows Phone 8 hurt sales of Nokia's Windows Phone 7 phones, plus it was a risky move for Microsoft which "can ill afford to alienate people when there are scores of highly capable and affordable Android phones up for grabs, or years-old Apple iPhones which aren't being prematurely shut out of the iOS playground." Poor performance led Nokia to sell its mobile phone division to Microsoft in 2013.
