E3, the Electronic Entertainment Expo, was in full swing in Los Angeles this week. The annual trade show for the video game industry was not without a few surprises, a few disappointments and as usual a few companies that opted to forego the whole thing. Sony was among the companies that chose to skip the event, while rival Microsoft was present only via its annual press conference.

Microsoft whetted the appetite of power-hungry Xbox gamers at its E3 preview, with new details about its next-generation gaming console code-named "Project Scarlett." Expected to arrive in time for the 2020 holidays, the new Xbox will have a custom-designed AMD processor based on the latest Zen 2 and Radeon RDNA technology. Scarlett also will have high-bandwidth GDDR6 memory and a next-gen SSD.

Apple has refreshed its iPod touch line of media players with a faster processor, greater storage capacity and improved communications features. The new iPod is built on Apple's A10 Fusion chip, the same processor used in the iPhone 7. According to Apple, the power upgrade delivers two times faster performance than previous models and three times better graphics.

It is expected that 5G will move aggressively into the market, with near-complete major metropolitan coverage by the end of the year. This technology is a game-changer, but it doesn't come without issues, one of which is the massive change in network loading. 5G will shift the bottlenecks from the wireless networks to the backhaul, where the expected massive increase in traffic will force some rather impressive network upgrades.

New augmented reality features, an SDK for Stories, and a games platform highlighted Snapchat's first developer's conference. AR features announced at Snap's first Partner Summit: solving math problems by pointing the app's camera at them; AR effects for monuments, pets and people; buying what the camera sees through Amazon; and identifying songs through Shazam.

Apple announced a raft of new services, including original TV programming and news and magazine offerings, at an event held at the Steve Jobs Theater in Cupertino, California. The Apple TV+ service, which will launch in the fall, already has a number of high-profile shows in its lineup, including Amazing Stories, a science fiction anthology produced by Steven Spielberg.

Facebook unveiled its Oculus Rift S virtual reality headset at the Game Developers Conference in San Francisco. It will be available this spring for $399. With the Rift 2, Oculus "is following some of the trends set by Vive -- inside-out tracking, incremental improvement, and focus on comfort," observed David MacQueen, executive director of Strategy Analytics' wireless media strategies service.

Google has pulled the wraps off Stadia, a new cloud-based gaming platform. Using the power of Google's global information infrastructure, Stadia can stream the highest-quality games to any screen, Google CEO Sundar Pichai said in announcing the platform, which is expected to come online later this year. Stadia represents Google's vision for the future of gaming.

Amid shifting consumer habits and the digitization of everything, the retail landscape has undergone significant transformations over the past decade, and it continues to evolve as quickly as ever. These transformations bring about a slew of challenges and opportunities for retailers to improve the overall shopping experience. One technique for increasing engagement is gamification.

Niantic last week offered a few members of the gaming press a chance to take in the magic of its upcoming Harry Potter: Wizards Unite augmented reality game. The game, which is being developed as part of a joint effort with WB Games San Francisco under the Portkey Games label, promises to build on Niantic's hugely popular Pokémon Go mobile phone game.

Microsoft CEO Satya Nadella has defended the company's $479 million contract with the U.S. military -- a commitment that some Microsoft employees strongly opposed. While pledging to engage with employees and consider Microsoft's role as a corporate citizen, Nadella said the company would not withhold technology from institutions in democracies elected to preserve the freedoms of their citizens.

A "Netflix for Games" type of service may be in Apple's future. Apple has been developing a subscription service that will function for games much like Netflix does for movies and TV series, according to a report. It's still unclear what the subscription fee would be or what kinds of games would be offered on the service. Whatever the fee for the offering, it could be tough for Apple to find an audience for a streaming service.

Verizon has a new cloud-based gaming service that is in the alpha testing stage, being tested on Nvidia Shield set-top boxes. The Shield devices, which were unveiled in 2015, were updated two years ago when Nvidia rolled out its own streaming service. Verizon Gaming will give greater software support to the Nvidia Shield, but it also will be opened to Android smartphones in the near future.

Nvidia has announced a breakthrough in 3D rendering research that may have far-reaching ramifications for future virtual worlds. A team led by Nvidia VP Bryan Catanzaro discovered a way to use a neural network to render synthetic 3D environments in real time, using a model trained on real-world videos. With Nvidia's technology, worlds can be populated with objects "learned" from video input.

When the Oculus Rift launched in 2014, industry stakeholders speculated that the new, high-end in-home virtual reality headset would disrupt the entertainment industry. Just four years later, the technology has reached a crossroads, still lacking adoption by mainstream consumers. In a recent survey, 25 percent of broadband households indicated they were familiar with some type of VR technology, but just 8 percent actually owned a headset.

After taking Battlefield to "the beginning" with the First World War-based Battlefield 1, developers have returned the action to World War II with Battlefield V. Anyone who's not familiar with this first-person shooter need know only that the original game, introduced in 2002 as Battlefield 1942, offers players the chance to control vehicles as well as soldiers.

Although retailers are slating some outstanding deals for Black Friday, the shine of the once-feverish shopping day has diminished, as product discounts have started to appear earlier and earlier in the holiday season. Discounts formerly found exclusively on Black Friday -- and on its online equivalent, Cyber Monday -- gradually have migrated to earlier in the fall.

When I read the book Ready Player One, I really got excited about the future of virtual reality, but the movie really didn't do the book justice. Some blockbusters have succeeded in interspersing computer graphics with real people and making it hard to tell the difference. Still, a totally rendered movie still looks like animation and you just don't get the film quality you get from, well, film.

Nvidia has announced a powerful new graphics architecture with the potential to blur the line between virtual and actual reality. Nvidia CEO Jensen Huang unveiled the new chips at the company's SIGGRAPH 2018 event in Vancouver, Canada. The Turing architecture enables a new generation of hybrid rendering that can be used to create cinematic-quality interactive experiences.

Samsung unveiled its much-anticipated Galaxy Note9 Thursday at its Unpacked event in New York City. The company made several other announcements as well, as it presented its vision for a seamlessly connected world. "We are creating a galaxy of experiences that span not just devices and locations but platforms and brands," said DJ Koh, CEO of Samsung Electronics, at the event.

A major "sporting event" aired on ESPN, Disney XD and ABC last weekend. It wasn't the recently completed FIFA World Cup, the finale of the Tour de France or the MLB All-Star Game. It was the Overwatch League Grand Finals -- the biggest e-sports championship to date. Much of the competition was "broadcast" via the online service Twitch, but on July 11 the Overwatch League announced a new deal.

It's interesting to compare Google and Amazon -- two of the most incredibly powerful companies in the world. Amazon brings out product after product, with more successes than failures. Google largely buys companies and then loses interest in what they do. Profit is built into Amazon's retail efforts, while Google largely lives off selling users' information and providing access to content.

E3 had the usual hits and misses this year, and more drama than most of the games on the screens. With a strong lineup of first-party titles plus better third-party support, Nintendo is the comeback king. However, the battle for hardcore gamer dollars continues to be fought between Microsoft and Sony. With no new hardware news from the companies, this was another year about the games.

Nintendo called in fan favorites, including Mario and Smash Bros., at this year's Electronic Entertainment Expo in Los Angeles. Super Mario Party will be heading to the Nintendo Switch this October, joined by Fire Emblem: Three Houses and the giant robot combat game Daemon x Machina. However, it was Fortnite that arguably stole Nintendo's E3 Direct show.

Sony gave PlayStation fans a hefty sampling of what's coming to its gaming consoles this year at E3. It gave them a long look at a relatively few offerings -- a marked contrast from Microsoft's deluge of titles. "Sony's E3 event was a break with tradition, an experiment to test the way it could present its first-party output to the media," said Piers Harding-Rolls, head of games at IHS Technology.

Microsoft made a big splash at the Electronic Entertainment Expo in Los Angeles with its announcement of more than 50 games for its Xbox One gaming console. Among the games unveiled by the company were 18 designed to run exclusively on Xbox, including Forza Horizon 4, Halo Infinite, Gears 5, Session, Below and Ashen.

The popular first-person shooter video game franchise Battlefield, which made its debut almost 16 years ago, will return to its World War II roots this summer. Battlefield V was unveiled this week in an online presentation hosted by comedian Trevor Noah, who sat down with the game's development team and discussed what gamers can expect when the title arrives this fall.

Microsoft has introduced its new Xbox Adaptive Controller, designed specifically for gamers with disabilities. The new hardware can be used for game play with an Xbox One console or Windows 10 PC, and it offers Bluetooth plug-and-play compatibility. It supports Xbox Wireless Controller features such as button remapping, and it connects to external buttons, switches, joysticks and mounts.

Devices built on Nvidia's Tegra X-1 mobile processor are at risk of attack from a flaw security researchers have revealed. The exploit chain discovered by Katherine Temkin and others affects any device running the chip, including the Nintendo Switch gaming console. Called "Fusée Gelée," the vulnerability allows anyone to run code on the chip by overloading a critical buffer when a system boots.

Valve has been working to reassure members of its community that it has not yet thrown in the towel on SteamOS and Linux gaming systems that have been hampered over the years due to performance issues, soaring sales on mainstream rival platforms, and generally weak demand. Valve recently withdrew SteamOS machines from its direct online sales portal.
