What are some resources to watch example pitches?

A previous Answers.OnStartups question asked about the best startup pitches people had seen. Worth taking a look through.

Some other resources for startup pitches are:

• http://pitches.techcrunch.com/
• http://www.virgin.com/entrepreneur/pitchtv/
• http://vator.tv/

And conferences like DEMO and TechCrunch 40 / 50 usually have pitches that are a lot more prepared for (but not necessarily better than) the pitches on sites where anyone can upload.

• http://www.demo.com/
• http://www.techcrunch50.com/2009/companies/
• http://www.techcrunch50.com/2008/video.php

That's probably enough video to keep you busy for years. Don't spend all your time watching other people's presentations. Read up at http://slideology.com and http://presentationzen.com, make a first version of your pitch, and put it up at the first three sites; improve it by getting feedback.
