Alphabet Inc (NASDAQ:GOOG) has reported first-quarter revenue below expectations as advertising sales for the owner of Google and YouTube were pressured by supply-chain and inflation concerns and the war in Ukraine. Alphabet said first-quarter sales were $68.01 billion, 23% higher than last year but below the average estimate of $68.1 billion, the company's first miss since the fourth quarter of 2019 before the coronavirus pandemic, while its total costs also increased by 23%.
