Wall Street Journal: DailyMail.com is investing $3 million in the content recommendation firm Taboola as the companies plan to develop advertising products together, including several that are geared toward improving the performance of sponsor-produced content. Taboola just received a whopping $117 million funding infusion from investors earlier this year. So another $3 million from DailyMail.com is hardly going to make or break the Israeli-founded company, which is now based in New York.
