WASHINGTON, May 13 (Reuters) - Video sharing platform

Rumble said on Monday it has sued Google,

arguing the tech giant has engaged in anticompetitive practices

across its digital advertising products and sought damages in

excess of $1 billion.

The suit alleges Google has monopolized the ad stack "by

buying companies up and down the chain, concurrently

representing both ad buyers and sellers, while also running the

exchange that connects those parties."

Rumble has accused Google of maintaining its monopoly by

reaching an agreement with Meta's Facebook to prevent

Facebook from offering alternatives to Google's ad tech

ecosystem.

Google did not immediately respond to a Reuters' request

for comment on the lawsuit.

Rumble filed the suit late on Monday in the U.S.

District Court for the Northern District of California.

This is the second time Rumble has filed a lawsuit

against Google. The earlier suit filed in 2021 accused the

company of favoring itself and its video sharing platform,

YouTube, in its search results.

The U.S. Justice Department also

filed an advertising

lawsuit against Google last year accusing the company of

abusing its dominance of the digital advertising business and

argued that it should be forced to sell its ad manager suite.

Google's advertising business is responsible for about

three quarters of its revenue.
