The information on the pages below contain basic information about the characters and concepts in Doctor Who. My hope is that the information you read here will help anyone who is starting to watch the first season of the new series (2005, with Christopher Eccleston as the Doctor) understand what’s going on in the show without revealing much about what’s coming up. In very specific, these articles contain no references to things that happen in the 2005 season or later. All links refer back to these articles, so you’re not spoiled by other pages on this site.
I’ve tried to avoid spoilers as much as possible, but please note that it’s hard to decide what’s a spoiler and what’s not. For example, is the fact that the Doctor a Time Lord a spoiler? It’s his species and very important to know, but at some point during the first couple of episodes, someone does say that he’s a Time Lord, and then explains something about that. Some might consider knowing that before it’s actually stated a spoiler, but I don’t think so.
