The Internet Archive added TV News to its collection yesterday, (Tues.18th Sept). The Archive has captured captured all (US) news from 20 channels. This is the start of something big and and I hope they will be adding news broadcasts from other countries soon, it is also good to see BBC Worldwide included in the aggregated content.
There is a lot here and to make best use, you would probably need to have a question, topic or search strategy prepared. You can search by keyword, time, program and TV network. There is also a useful word cloud that show recent searches. According Brewster Khale, founder of the internet Archive, this is just the beginning. The copyright debate that is likely to ensue should also prove interesting.
