The 200 lay-offs announced by Discovery Communications last week affected the US corporate and international divisions, education and US networks. There have been no retrenchments in Asia or any of the other regional offices thus far. However new Chief Executive David Zaslav has said the reorganization isn’t over and he’s hoping to have it completed by mid-year. Also concerning Discovery, don’t expect to see Discovery PlanetGreen rolled out overseas concurrent with or close to its US launch in 2008. A multiplatform initiative which entails the re-branding of Discovery Home Channel as the first 24-hour network dedicated to green lifestyle programming, Discovery PlanetGreen is a US domestic venture, at least for now. But it wouldn’t be surprising if the channel launched in some form in international markets, including Asia, down the track.
