Lets say I open site about mobile phones or about cars for instance. Site would be updated with the news then. So where do I get those news legally? I mean there are thousands of those sites and they get the news to update from somewhere
Generally, tech websites have news feeds. however, you can go here (as an example) and it will tell you how to get only news updates for say, the technology portion of cnn, and then you can specify only news updates for articles about cell phones.
CNN get their news from the associated press (ap) so you can go to ap.org (I think) or search for the associated press on msn/yahoo ( I like the small guys) and they have free rss feeds, I think they will be more detailed than cnn.
