Swiss-based Zattoo has announced the launch of an iPad app for streaming web TV in Germany... The offer includes channels from public broadcasters such as ARD Das Erste, ZDF, all so-called ‘third channels’ from ARD, Arte, Phoenix and BR Alpha. The private channels are restricted to Das Vierte, Sport 1 and iMusic, as apparently no deal could be reach with the two big commercial broadcasters, RTL Group and ProSiebenSat.1
