Zattoo, dually based in Zurich and Ann Arbor, sounds a bit like P2P TV efforts we’ve recently reviewed such as UUSee and MediaZone. ¶ And of course, there are the inevitable comparisons to fellow European contenders Joost and Babelgum. In Zattoo’s case, the core difference is that programs are not time-shifted, but shown linearly in the same way they are on TV, currently including the existing interstitial ads. ¶ Zattoo, which is based on research done at the University of Michigan, doesn’t currently have any channels available outside of Switzerland, somewhat hindering our review. However, initial testers such as blogger Bruno Giussani say they’re impressed.
