Apple, the most valuable company of them all, is set to disclose its numbers for the April-June quarter later today.
The quarterly earnings reports came a day after the Big Four's top executives faced a tough congressional grilling over their market power and alleged monopolistic practices.
A first for Google
Alphabet, Google's holding company, reported its first drop in quarterly revenue compared to the previous year. Although it was only a 2 per cent decline, it was a telling sign of a downturn in the digital ad market while also serving as a reminder that the economy is struggling even more than it did more than a decade ago during the Great Recession.
Google's low point during the GFC came during the second quarter of 2009 when its revenue edged up by just 3 per cent. Alphabet's profit for its most recent quarter plunged 30 per cent to $6.7 billion.
Facebook, which also makes most of its money from digital ads, recorded an 11 per cent increase in revenue from the previous year, the social networking company's slowest growth since going public eight years ago.
Its profit nearly doubled to rougly $6 billion from the same time last year. Part of the big jump stemmed from special charges last year.
