Yesterday (24 July), Alphabet (NASDAQ: GOOG, GOOGL) announced financial results for the quarter ended June 30, 2017. Alphabet reported a 21% leap in quarterly revenue, a growth rate rarely seen among companies its size and one that suggests the big sales gains enjoyed recently by the other internet firms are not done yet. 

"With revenues of USD$26bn (£20bn), up 21% versus the second quarter of 2016, and 23% on a constant currency basis, we're delivering strong growth with great underlying momentum, while continuing to make focused investments in new revenue streams", said Ruth Porat, CFO, Alphabet.

The profit would have been much larger, but for a record USD$2.7bn (£2bn) European Union antitrust fine. US antitrust enforcers thus far have chosen not to follow Europe's lead.

Alphabet noted that costs were rising faster than sales and warned that expenses would remain high as more searches shift to mobile devices.

Alphabet's cost of revenue, a measure of how much money the company must spend to keep its platforms running before added costs, such as research, rose 28%, well above the growth in revenue itself.

YouTube’s brand safety issues don’t appear to be slowing Alphabets's ad business. In fact, the company's revenue growth was powered mainly by YouTube ads and mobile search ads.
