"The UK's competition watchdog has launched an investigation into Google to assess its dominance in online search, as it accounts for 90% of UK web searches. The Competition and Markets Authority will investigate if Google is harming competition or choice for users and if it is using its position to prevent rivals from innovating. Google faces potential changes, including sharing data with other businesses or giving publishers more control over their data, as the investigation must be completed within nine months. The investigation is the first under the new Digital Markets, Competition and Consumers Act, which allows the CMA to impose rules on firms with strategic market status."
