In the U.S., tech companies get the most news coverage. Apple, Google, Amazon, Facebook and Microsoft are in the top 10 for daily articles carried on the Bloomberg system.

The news flow of the tech giants shows different patterns, however. My key takeaways:

-Apple garners the most coverage with surprising volatility
-Amazon shows a gradual, steady increase in coverage
-FB’s chart dominated by the Cambridge Analytica event
-Google is fairly consistent with spikes for earnings
-Microsoft shows steady coverage with few spikes
