Collaboration technologies Development of communication technologies IT -> ICT TV/radio -> telephon -> computer supported cooperative work same/different place same/different time

Groupware questions additional work for the individuals vs benefit prisoner’s dilemma critical mass may not handle exceptions and improvisation evaluation is close to impossible requires much adoption

Technical infrastructure Internet, 5G heterogenity in network conditions is problematic web2.0: helps bridging hardware/OS differnces (e.g. browser-based IM tools) smartphone, tablet, smart watch vary in computational power, display size, connection reliability etc…

e-mail First successfull computer supported communication technology PC, smartphone, smartTV, public terminals… spam, virus, malware etc communication differences between f2f and e-mail! power of people, tone interpretation information overload automatic categorisation/spam filtering tagging, importance ranking (explanation?) supporting e-mail composition (e.g. missing attachment)
