compatible with its earlier versions

OtW case studies

Case study:
South Korea

Why?
Many sites broke when Vista was
released??
SSL/TLS Active X
South Koreans are locked into Active X

Case study: India

UNICODE
EOT FONTS
legacy issue, sites used EOT fonts which is only supported in IE. Unicode is now the preferred
choice but it is complicated to migrate

Case study: China

Bank
Airline
Alipay
most banks, flight bookings, and ebay-like sites need ActiveX
