Tech giant Google spent $21.7 million on lobbying efforts last year to influence lawmakers as the government and regulators sought great scrutiny from tech companies related to users' privacy and unfair market practices.
According to a CNBC report on Sunday, Google has been the top spender on lobbying for two consecutive years.
"Amazon and Facebook also reached record levels of lobbying expenditures in 2018," said the report, quoting the Centre for Responsive Politics.
Amazon spent $14.4 million on lobbying while Facebook spent $12.6 million. Microsoft spent $9.6 million and Apple $6.68 million in 2018.
In a stern warning to tech giants earlier this month, the US House's anti-trust committee opened probes into Facebook, Google, Apple, Amazon and other firms to determine if they prevent competition and hurt consumers.
