Search and advertising giant Google has taken one more step in relegating Flash to the pages of history. From July this year, it will no longer accept Flash display ads.
From June 30, developers with Flash-based display ads can forget uploading them to Google's AdWords and DoubleClick Digital Marketing. Instead, they'll need to output display ads in HTML5.
