Google, Facebook, Amazon and eBay are joining forces to create a powerful pro-internet lobbying group in the US.
The Internet Association, as the group will be known, will launch in September and operate out of Washington, handling political and regulatory issues.
Both Google and Facebook currently spend large amounts of money on political lobbying.
Lobbying is a big industry in the US, with an estimated $3.3bn spent trying to influence lawmakers last year.
According to the Center for Responsive Politics, Google has spent $5.4m (£3.4m) on lobbying so far in 2012. In the same time frame Facebook spent $650,000.
The group would "educate" lawmakers about the internet, said new president Michael Beckerman.
Mr Beckerman is a former adviser to the chairman of the House of Representatives Energy And Commerce Committee.
"We want to educate [lawmakers] about the impact of the internet in their congressional districts," he said.
The full list of companies joining the group and the issues they would focus on would be announced in September, he added.
The issues net firms lobby on range from immigration reform - to make it easier to hire foreign engineers, taxes, privacy and cybersecurity.
Legislation such as the Stop Online Piracy Act and the Protect IP Act drew huge criticism from the industry, with firms saying the plans undermined the freedom of the internet.
Online protests reached a head in January with sites such as Wikipedia temporarily shutting down. Both bills are currently on hold.
