The UK's Competition Markets Authority has designated Google as having Strategic Market Status, meaning the company has substantial and entrenched market power. According to a new regulation filed on Friday, suggestions to fix this designation could change how the online search giant operates within the country. Google also faces scrutiny in the US over its market share. A federal judge stopped short of ordering the firm broken up earlier this year in a lawsuit over its search business. In another case, a different judge determined the company was operating a monopoly in its advertising business. Don't miss any of our unbiased tech content and lab-based reviews.

Since Google has a dominant position in online search in the UK, with over 90% market share, the CMA is suggesting that Google give users "choice screens" in Chrome to allow people to opt for competing search engines. It also highlights concerns from publishers regarding ranking and the use of content for AI-generated summaries. At the moment, changes don't have to be made to Google's use of AI Overviews, but a future designation could be made. When asked for comment, both Google and the CMA linked to their respective blog posts. "By promoting competition in digital markets like search and search advertising, we can unlock opportunities for businesses big and small to support innovation and growth, driving investment across the UK economy," said Will Hayter, executive director for digital markets at the CMA, in a blog post. The blog post also notes that Google hasn't been found guilty of wrongdoing, but this designation enables the CMA to take steps to ensure fair competition. "The UK enjoys access to the latest products and services before other countries because it has so far avoided costly restrictions on popular services, such as Search," said Oliver Bethell, senior director of competition at Google, in a blog post. "Retaining this position means avoiding unduly onerous regulations and learning from the negative results seen in other jurisdictions, which have cost businesses an estimated €114 billion."
