There are all sorts of free Lectures and Talks on the web.
In this article I want to take a look at specific examples of lectures and some of the main sites. These sites cover all sorts of subjects at all levels, from hobbies and general interest right up to Degree level and beyond!
Let's start with an example of a general interest talk.
Joe Costello is the CEO of think3 and he presented the talk "So You Want to Be an Entrepreneur" to the University of California. www.coe.berkeley.edu/multimedia/. It's a motivational type lecture, ... how to make the most out of what you've got for in business, research, or other aspects of your life. And he does it in a very entertaining way! The lecture lasts about 50 minutes with a 20 minute question and answer session.
Lower Quality Video higher quality visuals!
The Costello lecture is above average in terms of video quality, and you can even run it full screen and it looks fine. A lot of lectures on the net don't have quite the same quality but there can be compensations.
For example the "Chance Lecture Series". The video on these is very small but the layout is very interesting.
At the bottom right of the webpage to the right you see the video and the rest of the page what is showing on the overhead projector. The slides change at exactly the same time that the lecturer changes the acetate. This particular lecture is called Streaks in Sports and you will find it on the Chance Lecture page under the heading 1998 Chance Lecture Series. Tom Gilovich of
Cornell University discusses in particular the idea of the "hot hand" in basket ball and using statistics comes to some rather interesting conclusions. These are relevent to other sports and in addition, he's an entertaining speaker so it's well worth a watch.
You can see Tom Gilovich bottom putting a slide on the overhead projecter. In real life it is showing to his right and he is looking up at it and explaining it.
As the viewer you get to see this slide for real right on your browser so the quality is excellent! There are numerous lectures on the page. They are all related in some way to probability and statitics.

IDS 110 Introduction
http://mitworld.mit.edu/ - Is a free and open educational resource "for educators, students, and self-learners around the world."
It provides free searchable, access to MIT's course materials. There are 1,400 courses published so far with more to come.
One of the stars of the the MIT Open Courseware is Walter Lewin who teaches Physics. His video lectures cover every aspect of physics from fun packed wacky experiment heavy public lectures right up to the most advanced way out stuff. And the lectures also come with all the course materials included. The easiest way to find all of his lectures is just to type Lewin in the main course index. You will see that there are 81 results!
There are 6 great lectures also at MIT World including 6. The Wonders of Electricity and Magnetism: "The inimitable Walter Lewin gives a literally hair-raising performance in this MIT Museum lecture/demonstration for learners young and old. He unveils the real meaning behind words and things most of us use everyday without reflecting on what marvels they really represent. Lewin indulges the armchair physicist who's mathematically challenged, by covering all the basics of electricity and magnetism while introducing just one equation. If you're still undecided, check out some of the unique special effects - sparks, flashes, smashes, and more!"
8.01 Physics I - Professor Lewin puts his life on the line in Lecture #11 by demonstrating his faith in the Conservation of Mechanical Energy.

A good tip to find more lectures on the web is to use a search engine for terms such as webcast, skypecast, netcast, audiocast, archived lectures etc. in a search engine
In Google, to just bring up results from universities you can use this search query:
Another great way is to type lecture and say economics or whatever subject you are are interested in to http://video.google.co.uk/
