Sales at the tech giants Alphabet and Microsoft have slowed sharply, adding to fears of a downturn in the economy.
Alphabet, which owns Google and YouTube, said sales rose just 6% in the three months to September, to $69bn, as firms cut their advertising budgets.
It marked the US firm’s weakest quarterly growth in nearly a decade outside of the start of the pandemic.
Microsoft meanwhile said demand for its computers and other technology had weakened.
Its sales rose by 11% to $50.1bn, marking its slowest revenue growth in five years.
Consumers and businesses around the world are cutting back as prices rise and interest rates go up, fuelling fears of a global recession.
Profits at Alphabet dropped nearly 30% to $13.9bn in the quarter, as YouTube ad revenues declined for the first time since the firm started to report them publicly.
Sales growth at the firm has slowed for five consecutive quarters.
Boss Sundar Pichai said that Alphabet was “sharpening” its focus and “being responsive to the economic environment”.
“This disappointing quarter for Google signifies hard times ahead if market conditions continue to deteriorate.”
