Don't kill your television--study it!

| I just learned about a link that's apparently been live for a while, but it's
| new to me: [url]http://sony.com/linux[/url]. Following that link one level to Television
| you'll see that SONY has been embedding GPL software into their
| state-of-the-art televisions since 2003.
Linux device links TVs to Internet videos
,----[ Quote ]
| Sony used Linux to build an IP set-top box (STB) that connects to its Bravia
| HDTVs, enabling them to display a regularly updated selection of Internet
| videos. Sony's DMX-NV1 Bravia Internet Video Link is equipped with Ethernet,
| HDMI, and proprietary USB-based DMeX connections.

Embedded Linux has more friends than you may know
,----[ Quote ]
| Sony recently announced that one of its BRAVIA LCD TV factories will double
| production from 2 million TV sets per year to 4 million to meet growing
| demand in Europe. Sony has sold more than 20 million of these TVs, and
| they're all built with embedded Linux.
| So what? Embedded Linux is no surprise. Sony and tens of thousands of other
| companies, from huge to tiny, use embedded Linux every day to deliver
| successful products in every market. That is not news.
| Ten years ago, though, embedded Linux was a surprising-even shocking-idea to
| most people. Back in 1998, fresh from victory in the RTOS industry, I
| introduced the idea of building a software company to make Linux a suitable
| OS for developing smart devices. When I told people the idea, they gawked as
| if I was a few lines short of compilable code.
| "You want to build a company on software that's available for free?" I was
| asked. "Based on the gigantically bloated Unix OS? And with some oddball GPL
| license? How fast do you expect people to kick you out of their office?"
| Every market survey showed that the demand for embedded Linux was zero. When
| we released our first product, industry experts agreed that nobody needed it.
| Embedded Linux won't work because it is "too big, too slow, and not
| real-time," said the head of one RTOS company. The president of another
| derided embedded Linux as "a royal pain in the ass," so no developer would
| ever use it.
| I took heart from a quote attributed to Mohandas Gandhi: "First they ignore
| you. Then they laugh at you. Then they fight you. Then you win."
| Analyst firms don't agree on how many device engineers use embedded Linux,
| but they all say the number is substantial: 21% of developers use embedded
| Linux, according to last year's Embedded Systems Design survey; 36.7%,
| according to current research by Embedded Market Forecasters. This April, VDC
| reported that Linux is now the leading embedded OS. It shouldn't be
| surprising. After all, commercial Linux vendors succeed because they
| understand what design engineers are looking for.
