Roblox on Tuesday launched a new format of video advertising on its gaming platform and announced a partnership with Google to help boost the growth of its nascent ad business.

Video game maker Roblox said on Monday that it is implementing new safety measures for users under 13, including permanently removing the ability to message others outside games on its platform.

The lawsuits allege that Roblox prioritized its profits over child safety. The gaming platform rebuts claims it would intentionally risk the safety of its users.
