Bubble Motion recently launched a Twitter-like voice blogging service for mobile phones, dubbed "Bubbly," has seen considerable traction in India. Bollywood celebs including Aamir Khan and Kareena Kapoor being early adopters. Bubbly is growing virally and with virtually zero marketing spend, has accumulated more than 2 million overall users and currently has over 1.2 million paid subscribers across multiple telecom operators in India. And Bubble Motion is adding 100,000 new paid users per week.
Here's how it works: "Anyone can sign up to follow friend, family member or favorite celebrity or brand. Posting messages and following is free, once a new message is recorded and sent out, users get alerts. If they choose to listen, they pay for airtime. Most messages are less than 30 seconds long, with current cap of one minute. To post on Bubbly, a user dials a short code, like *7, records a message and hangs up. To listen, tap in another code, like *2. It works on any handheld device, and messages can be posted to Bubbly while still withholding phone numbers for privacy."
