As widely expected by Apple-watchers, iPhone sales have fallen for the first time ever.
Apple announced that not only had sales of the handset dropped, but that revenue also took a dive for the first time in 13 years.
This marks an end to an amazing growth streak that helped Apple become the world's biggest listed company.
iPhone sales for the most recent quarter were down from 61 million last year to 51 million. iPad sales were also down.
The company's overall sales were $50.6 billion (£34.7 billion) for the three months to the end of March. That's a decline of 13% on the same period last year.
Apple had previously warned that revenues would fall, but the results were a little worse than expected. And the storm isn't over yet; the firm expects sales to drop again in the current quarter.
However, the performance of Apple's Services division, which includes sales of apps and music, was a positive note for the tech giant.
Revenue from this division grew 20% in the last quarter, and now accounts for more income than both the iPad and Mac.
CEO Tim Cook was optimistic about Apple's future.
"Our team executed extremely well in the face of strong macroeconomic headwinds," he said.
"We are very happy with the continued strong growth in revenue from Services, thanks to the incredible strength of the Apple ecosystem and our growing base of over one billion active devices."
The firm still refused to divulge sales of the Apple Watch, suggesting that they haven't been as high as expected.
