This document summarizes internet and advertising trends across Central and Eastern European markets based on a review by Gemius, an internet market research firm. It finds that online advertising is growing faster in CEE countries than in Western Europe, with growth rates of 35-50% annually. Internet and broadband penetration is increasing across the region but varies between countries, with Poland, Russia, and Ukraine showing higher rates than others. The document also examines blogging platforms and finds that local blogging sites dominate in CEE countries, though global platforms like Blogger are also popular. Measurement of blog audiences is challenging due to factors like single users accessing on multiple devices or accounts.
