According to most of the freemium gurus, freemium and free trial are not the same thing; the former is defined as having a level of service that is free forever. Obviously free trials are by definition not free forever.
Freemium is a new word. A similar concept is 'crippleware' - you can do everything but not print. Or you can print, but it'll have a watermark. Or you can only save at certain resolutions. Etc.
I guess they would have been called freemium if the word existed then.
