Microsoft's XBox One and Sony's Playstation 4 face off for the top console spot this Christmas, but how do their features compare?
These are dramatic new steps which will make the internet safer and better for children, a leading Internet safety expert writes.
The search engines have stepped up to the plate - their reforms will help remove video child abuse content more quickly and comprehensively.
Microsoft's XBox One has launched a week earlier than Sony's Playstation 4, but which console will do best in the Christmas shopping wars? The experts take a closer look.
"The Xbox One is the more ambitious console, but it just doesn’t quite manage to follow through on all of its potential. Yet.
"The PS4 on the other hand might have less media and voice control powers, but its beefier specs promise a slew of eye-watering exclusive titles further down the line."
"In terms of functionality, polish, and games, the Xbox One is the better console.
"The Xbox One is a better launch-day console than the PS4, but I don’t think we’ll see a real leader emerge for a year or two: Microsoft needs to push a lot of software patches, and Sony needs to publish some games that really take advantage of the PS4?s superior hardware."
"Microsoft has made bold promises of dedicated servers for multiplayer games and it has the track record to back them up.
"If online mutiplayer is more important to you than anything else, we'd be leaning towards the Xbox One."
"Both systems are evenly matched in many respects and should be able to usher in the next generation of gaming that the [Nintendo] Wii U hasn't been able to deliver."
The new Xbox One console costs £429, and comes with one controller. Here's what users can expect:
- Voice and gesture recognition
- 500GB hard drive
- Video recording capability of gaming - up to 30 seconds
- Snap feature allows users to run two applications at once
- Runs TV Kinect-powered
- Launches with three games: Dead Rising 3, a zombie survival game; Forza Motorsport 5

Microsoft's Nicola Hodson said online child abuse content is "an evolving problem", making it "difficult to say whether anyone has done enough".
Ms Hodson told ITV News: "There is always much more to do, so we welcome the focus and we will continue to work hard on this area.
"We're very, very passionate about keeping children safe".
Prime Minister David Cameron admitted there is "still more to be done" to remove child abuse images from the internet, but stressed "huge progress" has been made.
Speaking after a summit at Downing Street, Mr Cameron said: "It's worth remembering we were told that cleaning up searches when people search vile terms, we were told it couldn't be done and we were told it shouldn't be done, for reasons of free speech.
"Well, we're now being told by the industry it can be done and it will be done."
