met Meta will have to defend itself from antitrust claims after all By www.engadget.com Published On :: Wed, 13 Nov 2024 15:57:32 +0000 The Federal Trade Commission will get a chance to argue its case for Meta’s breakup in court. On Wednesday, US District Judge James Boasberg allowed the FTC’s lawsuit against the social media giant to move forward (PDF link). The FTC first sued Meta in 2020 in an attempt to force the company, then known as Facebook, to divest itself of Instagram and WhatsApp. Alongside dozens of attorneys general, the agency alleged Meta acquired the platforms in 2012 and 2014 to stifle growing competition in the social media market. This past April, Meta asked Judge Boasberg to dismiss the case. In addition to noting that the FTC had previously approved both acquisitions, Meta argued that the agency had failed to show that the company held monopoly power in the social networking services market, and that, in buying Instagram and WhatsApp, it had harmed consumers. Additionally, the company claimed that it had invested billions of dollars in both platforms and made them better as a result, to the benefit of social media users everywhere. While he did not entirely dismiss the lawsuit, Boasberg did force the FTC to narrow its case, dismissing an allegation that Facebook had provided preferential access to developers who agreed not to compete with it. “We are confident that the evidence at trial will show that the acquisitions of Instagram and WhatsApp have been good for competition and consumers. More than 10 years after the FTC reviewed and cleared these deals, and despite the overwhelming evidence that our services compete with YouTube, TikTok, X, Apple’s iMessage, and many others, the Commission is wrongly continuing to assert that no deal is ever truly final, and businesses can be punished for innovating,” a Meta spokesperson told Engadget. “We will review the opinion when it’s filed.” Judge Boasberg will meet with the two sides on November 25 to schedule the trial. The FTC lawsuit, it should be noted, was filed under the previous Trump administration, though whether it moves forward and in what form will depend on who President-elect Trump appoints to lead the agency.This article originally appeared on Engadget at https://www.engadget.com/big-tech/meta-will-have-to-defend-itself-from-antitrust-claims-after-all-155730259.html?src=rss Full Article Business Company Legal & Law Matters site|engadget provider_name|Engadget region|US language|en-US author_name|Igor Bonifacic
met Meta will reportedly bring ads to Threads as soon as January By www.engadget.com Published On :: Wed, 13 Nov 2024 18:30:44 +0000 Threads could start getting ads much sooner than Meta has let on. The company is now planning to bring ads to its newest app “early next year” with the first ads arriving in January of 2025, according to a new report in The Information. That suggests Meta is looking to start making money on the rapidly growing service far sooner than Meta executives have previously suggested. In August, when the app reached 200 million users, Mark Zuckerberg said Threads could become the company’s next billion-user service. He said making money off the app would be a "multi-year" effort. “All these new products, we ship them, and then there's a multi-year time horizon between scaling them and then scaling them into not just consumer experiences but very large businesses,” Zuckerberg said. In the company’s most recent earnings call, Meta CFO Susan Li said the company doesn’t “expect Threads to be a meaningful driver of 2025 revenue at this time.” According to The Information, Meta is planning a slow rollout for ads on Threads. The company will start with “a small number” of advertisers in January. It’s unclear how quickly the effort may expand. "Since our priority is to build consumer value first and foremost, there are no ads or monetization features currently on Threads," a Meta spokesperson said in a statement. Meta’s reported plans highlight just how quickly the service has grown in recent months. Threads has 275 million monthly users and is seeing more than 1 million new sign-ups a day, according to Zuckerberg. That makes it by far the largest of the X alternatives that have sprung up over the last couple years. Bluesky, another popular Twitter-like service, has also seen significant growth recently, adding a million new users in the last week, the company said Tuesday. It is still much smaller than Threads with 15 million users. Like Threads, it also currently has no advertising and the company has said it plans to experiment with subscription-based features. Update November 13, 2024, 2 PM ET: Added a statement from a Meta spokesperson.
