Amazon announced its fifth consecutive quarterly profit yesterday, and its third consecutive record-setting profit. Revenue increased 31 percent; sales rose to $30.4 billion from $23.19 billion. The company’s cloud computing division, Amazon Web Services, accounted for an impressive 56 percent of Amazon’s operating income, and it grew 58 percent in the last quarter. “The results show Amazon moving toward investors’ long-held hope of consistent profitability after a lengthy period of heavy investments and quarterly losses,” notes The Wall Street Journal. “Overall, Amazon posted a second-quarter $857 million profit, or $1.78 a share, compared with $92 million, or 19 cents a share, a year earlier.”
