According to London’s Daily Telegraph, citing a source familiar with the matter as saying, King.com, the London based maker of Candy Crush Saga has filed for an initial public offering with the Securities and Exchange Commission. The IPO aims to raise $5 billion. The year has been devoid of tech-related IPOs. According to a data provider, Dealogic, only one in six IPOs this year have been tech-related. The slowdown in tech-related IPOs is mainly due to Facebook’s (NASDAQ: FB) dud debut and drubbing of Zynga Inc. (NASDAQ: ZNGA) after its IPO in December 2011.
