Smartphones shake website world

Internet giants from Google and Facebook to Yahoo and Zynga are scrambling to adapt to an online world where people reach for smartphones or tablets instead of traditional computers.

Internet giants from Google and Facebook to Yahoo and Zynga are scrambling to adapt to an online world where people reach for smartphones or tablets instead of traditional computers.

Social games pioneer Zynga, which rose to stardom making titles played at Facebook's website, is cutting nearly a fifth of its staff as part of a move to focus on titles for mobile gadgets.

After taking over as chief executive at Yahoo last year, former Google executive Marissa Mayer laid out a turn-around strategy that made a priority of tailoring offerings to smartphones and tablets.

The dismal performance of Facebook's freshly-launched stock last year was blamed in large part on fears that it lacked tools to cash in on members who are increasingly accessing the social network from mobile devices.

Google has proved prescient by creating and giving away an Android mobile operating system that showcases its software and services on smartphones and tablets.

Industry data shows that people are moving "aggressively" to apps and away from traditional websites, according to Gartner.

Not only are the devices preferred by Internet users changing, so is their behavior.

Gartner research shows that people using smartphones access the Internet an average of 20 times a day with sessions lasting about a minute, compared with four times daily for about 35 minutes a pop on traditional computers.
