Facebook sells more access to its members [THE WALL STREET JOURNAL] To amp up the effectiveness of its ads, Facebook in recent months has begun allowing marketers to target ads at users based on the email address and phone number they list on their profiles, or based on their surfing habits on other sites. It has also started selling ads that follow Facebook members beyond the confines of the social network. “Like eating glass”: Sean Parker on Airtime’s bumpy launch, exec departures and more [ALL THINGS D] Along with executive turmoil — including the upcoming stepping back of tech lead Eric Feng and Shawn Fanning, Parker’s Napster co-founder, who was the CEO and driving force behind Airtime while Parker was focused on Spotify last year — there has also been a very weak launch in getting Airtime off the ground.
