Sen. Tom Cotton says it's time to revive competition and sharply limit further consolidations by Big Tech.

The Arkansas Republican made his comments in a column for Fox News on Tuesday.

"Google, Facebook, Amazon, and Apple are monopolistic technology corporations that dominate a greater market share in their fields than any similar firms in American history," he said.

"While size alone isn’t a problem, these firms have used their extraordinary wealth and power to buy up rivals, stifle competition and muzzle speech that they oppose. This harms Americans, and that’s why I have joined with Sen. Amy Klobuchar, D-Minn., to introduce the Competition and Opportunity Act, which would stop the further consolidation of these tech giants.

"Google controls more than 90% of the search market, Amazon controls 80% of the e-book market and a huge share of cloud services, Facebook controls a majority of social media, and Apple – along with Google – share total control of the App Store market."
