Orkut and Reader. Both from Google. Orkut was just toy product for Google. But considering the fan base (especially from India) they got I was surprised they did not continue it. It was at the time overshadowed by Myspace and later Facebook. Google reader was a nice RSS feeder. Many people was disappointed when Google declared that they were shutting it down. For both these products, I guess main reason from Google was that they were concentrated on other things at the time. But most important I think these were not matching with there advertisement based Revenue model.
