SLS Broadcast Research Pre and post test Two groups
• Experimental - claimed to watch regularly• Control - claimed to not watch
25 episodes (weeks) Results
• Showed some marginal literacy gains by theexperimental group over the control
• At an annual per-person cost of $0.00022• And viewers liked it!

Telecenters are common (ubiquitous?)
telecentre.org estimates > 60,000 worldwide• not counting schools, libraries, and commercial
cybercafes.• (telecentre.org is supported by Canada's International
Development Research Centre (IDRC), the Swiss Agencyfor Development and Cooperation (SDC), and MicrosoftUnlimited Potential program.)

Prototypical problems Economic barriers: fees vs. willingness to pay Social barriers: Discrimination or avoidance Confused branding: try to be all things to everyone Educational barriers: difficulty in text and computer
navigation Mistrust and overabundance of information Lack of information in a familiar form: e.g languags &
dialects Poor infrastructure: spotty electricity and connectivity Frequent maintenance needs: Quality service unavailable or
costly

Key findingsfrom http://research.microsoft.com/research/tem/kiosks
Meeting business needs and social developmentgoals simultaneously is difficult.
What rural villagers want and what we think theyneed are frequently different.
The kiosk entrepreneur plays the most critical rolein the success of a kiosk.
A kiosk champion can help sustain a set of kiosks. Services require attention to the entire supply chain,
not only to the kiosk. Focus on a single class of services increases
likelihood of success.

Key findingsfrom http://research.microsoft.com/research/tem/kiosks
Kiosks do better in towns; kiosks do better in remotevillages.
Kiosks in offices and schools may provide alternatives to thestandalone kiosk.
Kiosk usage is dominated by relatively affluent, moreeducated young men.
Per-transaction fees are resisted by many customers. Mobile-phone-based kiosks offer an alternative to PC-based
kiosks.
