TV 2.0 for Producers: The 101 of Web 2.0
Web 2.0? What happened to 1.0? When did they release the update and have I installed it?
There is no update, you don't need to install it, it's already here, and you're in it.
It's not a program, it's just how we're navigating the internet these days.
In the initial days of the internet (or world wide web) most people would find what they were looking for by typing in a website address/URL (www.dogfood.com) and being taken to the site's homepage. From the homepage, one would follow the available hyperlinks until they hopefully found what they were looking for. Each website, for the most part, was a destination and billions of dollars were spent marketing and promoting website brands, like "netzero: free internet forever" did during the super bowl.
That was Web 1.0
Nowadays, most websites are no longer destinations in and of themselves (though they would like to be.) We've entered the world of search. Search engines like Google and Yahoo have become common methods by which most people find what they're looking for. Now, instead of going to a website's homepage to find what you're looking for, one now plugs their query into a search engine and peruses amongst the results to find the most relevant. In most cases, these search results won't take you to the home page, but instead will take you directly to the relevant page within the site that corresponds with your initial search request.
The use of "search" to go directly to what you're looking for (thereby circumventing homepages and long trails of hyperlinks) is known as Web 2.0
