Ohhhhh hospital

The most useful source i have found has come from the method of internet research.

Wikipedia.org told me starting dates, number of episodes/seasons, cast members, cameo appearances and ratings.
I checked the where the ratings came from for authenticity and they came from reliable sources; Hollywood reporter, E!online, USA today and Geocities online. These however are the American ratings so I am going to look for UK ratings on BARB.

YouTube offered interesting comments in the comments section, however the video clips weren't full and were mostly fan videos.

I am currently looking for ER fan message boards to question fans on.
