Google and Amazon on a collision course

It was a tech industry tit for tat: First came word that Amazon is paying $1 billion for a video game streaming company Google had pursued. Three days later, Google announced a major effort to build aerial drones capable of delivering packages, something that Amazon has been conspicuously working on, too.

While Google competes with a number of tech rivals, the recent dueling announcements show the Mountain View, Calif., Internet giant and the Seattle e-commerce goliath are stepping on each others' toes with growing frequency, as they expand into new businesses from smartphones to streaming video, cloud computing and, most of all, digital advertising and online shopping.

Google and Amazon "are headed straight for the same destination. Each wants you to think of them first when you have any kind of need in the future," said James McQuivey, a tech industry analyst at Forrester Research.

At first glance, the two companies seem very different. Google makes most of its money by selling advertising. Amazon sells books, videos and all kinds of consumer goods.

But those businesses overlap: Google wants you to use its search engine when you are looking for places to buy Bluetooth speakers or hiking boots, so it can show you paid ads for those products. But studies show more shoppers are now using Amazon to search for products sold by the online retailer and its partners.

"The question is, where do consumers start when they are looking to buy online? Google was dominant for a long time, but Amazon has taken some of that over," said Scot Wingo, CEO of ChannelAdvisor, a company that helps retailers manage their online ads.

Some analysts say Amazon has gained an edge as consumers increasingly use smartphones and tablets. Shoppers who are signed into Amazon's mobile app can search for products and make purchases with a few clicks, without the laborious process of typing their shipping and billing information on a tiny screen.

The battle has expanded as both companies woo shoppers by offering convenient electronic payment and same-day delivery in some cities.

Both are also competing to sell digital entertainment, such as streaming video, downloadable music and e-books.

"Amazon and Google are in a dogfight for the hearts and minds and wallets of the online shopper," Wingo said.

Google doesn't say how much of its nearly $60 billion in yearly revenue comes from retail advertisers. But it acknowledges they are a key segment, which Wingo estimates may account for more than a third of Google's ad sales. Amazon had $74 billion in revenue last year, although its cost of goods and other expenses are so high that its profit was a paper-thin $274 million. Google's profit was nearly $13 billion.

The two companies are also competing outside their core businesses.

Amazon has even entered the mobile computing business, with Kindle tablets and a new Fire phone. Google promotes its Android operating software for smartphones and tablet so people will use its search engine and other ad-supported services. Similarly, despite reports that Fire phones aren't selling well, McQuivey said Amazon may find them valuable for testing new apps and tracking users' shopping habits.

And now both companies are touting the notion of using unmanned flying drones for deliveries.

"It looks like science fiction, but it's real," Amazon says on its website, which promises "we'll be ready" to offer aerial deliveries next year, if government authorities allow them.

That's unlikely. Most experts say it will take several years to refine the technology and the federal safety rules needed for commercial drone deliveries. Google has echoed those cautions, though it says drones could someday deliver disaster supplies or consumer packages.

Amazon struck a more immediate blow with its $1 billion deal to buy Twitch.tv, a popular video-game streaming service. Google wanted to add Twitch to its YouTube video platform. Analysts say Twitch commands a big audience of young gamers, male and female, who are desirable ad targets.

While neither company releases figures, Bernstein Research analyst Carlos Kirjner estimates Amazon's cloud computing business will bring in nearly $7 billion in revenue next year from customers including start-ups, big corporations and services like Netflix and Instagram.

Google's cloud service is newer and smaller; tenants include the popular Secret and Snapchat apps.

Tech observers say these battles are part of a bigger trend: Major Internet companies are all competing to provide a wide range of services in the hope that consumers won't switch to a rival company.

"These very big companies — Amazon, Google, Apple, Facebook — are all bumping into each other in different ways, as they get bigger and invest in different kinds of businesses," said Scott Kessler, Internet stocks analyst at S&P Capital IQ.
