San Francisco: Search engine giant Google will introduce a built-in ad blocker in the Chrome browser to block "annoying" advertisements from February 15. "This date does not appear to be tied to a specific Chrome version. Chrome 64 is currently scheduled to arrive on January 23 and Chrome 65 is slated to launch on March 6, suggesting Google will be turning on its browser's ad blocker remotely and possibly gradually for select users," Venture Beat reported late on Tuesday.
