Google Inc. announced that in its continuing effort to bring focus to its operations, it will shutter a half-dozen businesses--including Picnik. Since the middle of last year, Google's been on a slashing binge, cleaving under-performing and peripheral businesses from its portfolio. In October, it announced plans to kill its Buzz social network. In July, it discontinued Google Labs. And in June, it pulled the plug on Google Health. Picnik is probably the best-known of the services Google is killing. The company bought the company in March 2010, and plans to end the service on April 19. Picnik users can download a zip file of their creations through Picnik Takeout or copy them to Google+. And until its demise, Picnik's premium service is free, and its premium subscribers will receive full refunds. The company also closing Google Message Continuity, an email disaster recovery product for corporate customers that launched in December 2010. Instead, Google will be pushing its Google Apps business.
