When users sign up for free services from Microsoft and Yahoo, their information is being used for targeted political ads, ProPublica reports. The news probably doesn’t surprise anyone in the Internet age, and political-ad targeting has been around for a long time. But the report points to a key thing: The ability of companies such as Microsoft and Yahoo to provide this information to political campaigns is unprecedented. That’s thanks to cookies they place on Web browsers, which help track users.

Because of Microsoft and Yahoo’s broad reach, the resulting targeted ads can appear seemingly everywhere...

Google and Facebook reportedly do not engage in similar practices...
