Google remains a centerpiece of online activity, with offerings such as its search engine, ad marketplace, and YouTube video platform that give it extensive global influence.
Alphabet revenue of $65.1 billion in the recently-ended quarter eclipsed the same period last year by some 41 percent, according to the tech titan, as its online ad engine and cloud services thrived.
Fellow giant Facebook, despite its whistleblower scandal, has also announced whopping profits, as did Microsoft, although Twitter reported a large loss due to a shareholder lawsuit settlement.
''This quarter's results show how our (artificial intelligence) investments are enabling us to build more helpful products for people and our partners,'' said Sundar Pichai, CEO of Alphabet and Google.
''As the digital transformation and shift to hybrid work continue, our Cloud services are helping organizations collaborate,'' he added.
From July to September, its video service sold $7.2 billion of advertising space targeted according to content and users, against $5 billion in the same period last year, according to Alphabet.
Its remote-computing business saw nearly $5 billion in revenue, up 45 percent over the previous year.
