Krikorian, known for co-founding Sling Media in 2004, informed the rest of the board on Wednesday of his intention to resign, Amazon said in a Friday filing.
Spokesman Ty Rogers added that the serial entrepreneur, whose latest endeavor is home-automation startup id8 Group R2 Studios Inc, has sold a company and quit in order to take up a position at the acquirer. He did not name the company involved or the buyer.
The Wall Street Journal reported last week that Krikorian's year-old startup was in acquisition discussions with Amazon rivals Apple Inc, Google Inc and Microsoft Corp. It cited sources as saying the trio of tech powerhouses coveted R2 Studios' home-oriented technology as they expanded their own forays into living-room media entertainment.
R2 Studios recently launched a Google Android application to allow users to control home heating and lighting systems from their smartphone. Krikorian's Sling Media which was sold to EchoStar Communications in 2007 made the "Slingbox" for watching TV on computers.
Krikorian, known also for doing double duty as an angel investor, joined Amazon's board in September of last year, a move hailed as helping propel Amazon's own substantial efforts in online media.
