From PC World: Twitter is to acquire ZipDial Mobile Solutions, a Bangalore company that has developed a platform that allows content like promotions to be delivered to users through voice, SMS or an app notification when an user gives a missed call.
The technology takes its cue from the tendency for cost-conscious Indians to signal that they want to talk to someone by placing a call and hanging up before the phone is answered, with the expectation that the other person will then call them back.
The acquisition of the ZipDial platform and its various technologies to address consumers is likely to be useful for Twitter in emerging markets where data access is found to be expensive by consumers or is not easily available.
Users have to just give an advertiser a toll-free “missed call” to a designated phone number to receive content through any of the channels.
