Combined, Apple, Amazon, Facebook and Google devoted $50 million to lobbying efforts in 2017, according to CNBC.
Big tech advocated for issues ranging from immigration to net neutrality to a Congressional investigation on Russian propaganda on their sites. For many of these companies, last year marked their highest lobbying pricetags yet.
Here is a breakdown of the four technology companies' lobbying spending.
1. Google: $18 million. The company lobbied against regulations that targeted content and ads.
2. Amazon: $12.8 million. Amazon sought to advocate easier restrictions on online sales taxes, as well as cloud computing and package-delivery drones.
3. Facebook: $11.5 million. The social media company faced a lot of lawmakers' criticism for "fake news" and other content that infiltrates users' newsfeeds.
4. Apple: $7 million. Apple poured funds into issues like encryption and immigration, as well as the tax reform law.
