What are Intro's? - In short, they're small advertisements for BBS's (Bulletin Boards(remember them?)), or pirate/demo groups. Long answer: intro's are a blend of art and technology, they require programming finesse, a desire to produce the tightest, most efficient code, a large amount of skill, and a fair amount of artistic flair and talent. They are the bridge between the 'warezscene' and the demoscene.
