US officials have confirmed they are considering breaking up Google’s “illegal monopoly” of internet searches.
The tech giant could face restrictions on its own products – including its Chrome browser, Play Store and Android operating system, the US Justice Department said.
It comes after a judge found in August the company had broken anti-trust laws to ensure its dominance of online searches.
Officials have now outlined a series of proposals to dismantle the company’s monopoly in a court filing.
The plans include blocking Google from paying other tech firms to have its search engine pre-installed or set as the default option on new devices.
The firm paid out more than $26bn (£20bn) in 2021 to companies such as iPhone maker Apple as part of the practice.
A Justice Department spokesperson said: “Fully remedying these harms requires not only ending Google’s control of distribution today, but also ensuring Google cannot control the distribution of tomorrow.”
Google said the court filing was part of a “long process” and confirmed it would appeal against the ruling.
Lee-Anne Mulholland, the company’s vice president of regulatory affairs, said the “radical changes” proposed went too far and accused the US government of having a “sweeping agenda that will impact numerous industries and products”.
She added the move would risk the privacy and security of users, hamper the development of its artificial intelligence products and “break” software such as Android.
The government’s announcement comes following earlier reports that officials were considering moves to tackle Google’s monopoly.
Meanwhile, in a separate case on Monday, a judge ordered Google must open up its app store to greater competition, including making Android apps available from rival sources.
Judge James Donato said the firm should stop requiring its own payment system to be used for apps on the Play Store.
The ruling follows a court battle between Google and Epic Games, which makes the popular video game Fortnite, over in-app purchases.
