For decades, AT&T, Verizon, and other firms dating back to the old Bell System have known that the lead in their networks was a possible health risk to their workers and had the potential to leach into the nearby environment. They knew their employees working with lead regularly had high amounts of the metal in their blood, studies from the 1970s and ’80s show.

When choosing the best video clips to promote from around the web, Alphabet’s Google gives a secret advantage to one source in particular: itself. Or, more specifically, YouTube. Google executives in recent years made decisions to prioritize YouTube on the first page of search results, in part to drive traffic to YouTube rather than to competitors, and also to give YouTube more leverage in business deals with content providers seeking traffic for their videos. A Google spokeswoman, Lara Levin, said there is no preference given to YouTube or any other video provider in Google search.

Google has increasingly re-engineered and interfered with search results to a far greater degree than the company and its executives have acknowledged. Those actions often come in response to pressure from businesses, outside interest groups and governments around the world. They have increased sharply since the 2016 election and the rise of online misinformation. Google’s evolving approach marks a shift from its founding philosophy of “organizing the world’s information,” to one that is far more active in deciding how that information should appear.
