There are a great many online resources for those interested in philosophy and many other subjects. In particular, it is possible to take free online courses from major universities and to see lectures and presentations by philosophers and folk in related fields. If you want to find talks by a particular contemporary philosopher, sometimes the best way to proceed is just to do a search on his or her name. You can often refine the search by choosing "videos." If the individual has any online videos, that should bring them up. But I also want to include some particular sites. More lectures and courses are appearing all the time.
Open Yale Courses. http://oyc.yale.edu/. Yale has put online a number of courses, complete with lectures, including two philosophy courses, one on "Death" taught by Shelly Kagan and one titled "Philosophy and the Science of Human Nature" by Tamar Gendler.
Coursera. https://www.coursera.org/. a large number of universities, including Stanford, Princeton, the University of Pennsylvania and the University of Michigan (33 total) have joined together to offer real time courses, some in philosophy and related subjects. They are free but you must sign up for them and determine the days and hours each is taught.
Michael Sandel's Course "Justice." http://www.justiceharvard.org/. This course is advertised as one of the most popular courses in Harvard history.
Ted. www.ted.com. Ted hosts a large number of short lectures (under 20 minutes) given at Ted conferences around the world. The subjects are varied, but some are by philosophers or are relevant to philosophers. For example, there are several talks by social and political philosopher Michael Sandel including one on "The Lost Art of Democratic Debate" and another one titled "What isn't for Sale" in which he argues against the extension of the free market and its values into many areas of our lives. Two of my favorite Ted talks are "Are we in Control of Our Own Decisions?" (the answer is no) by behavioral economist Dan Ariely and "The Moral Roots of Liberals and Conservatives" by psychologist, Jonathan Haidt.
Youtube. There are a huge number of talks by philosophers and folks of interest to philosophers, some long and some short, on youtube. You can simply do searches on the names of particular contemporary philosophers or for particular subjects. For example, there is a series of lectures on youtube by Steven Stitch entitled "The Definition of Morality" in which he considers how traditional moral philosophy can be transformed by work in cognitive science. This can be found at https://www.youtube.com/watch?v=a5MqPm4nHto&list=UUaR4lVhkCip2px9ApGBpqXw&index=30&feature=plpp_video.
Philosophy Bites. http://philosophybites.com/. Put together by Nigel Warburton, this site is advertised as "podcasts of top philosophers interviewed on bite-sized topics."
