Last week, it came out that Amazon had increased the amount it spends on $4 by almost 10x from last year, to $9.07 million.
That puts Amazon in the number-three position in terms of lobbying by tech companies. As this chart from $4 shows, Google is by far and away the leader, and Facebook edged out Amazon for the number two spot.
Keep in mind that while these may seem like big numbers, they're a tiny part of these companies' overall expenditures - in the third quarter of 2015, Google spent $3.47 billion on traffic acquisition costs (such as the price of its deal to remain the $4), and another $6.93 billion on other operating expenses.
