E3 is a relic of a bygone age. It was made when internet video was pretty much impossible. And even as internet video picked up more, there was still some space for E3. But I say 2011 onward was the beginning of the end. The shows just aren't as exciting anymore for the most part. And in the past 5 or so years they've become increasingly irrelevant.
