It depends in which country you are living in.
In the UK, Russia and Australia - C-Bus In America - Lutron
Worldwide - Crestron (Expensive)
There are a large number of ways to do this - lots of people DIY it, but there are very simple commercial solutions out there too.
X10 is probably the best known standard.
Have a look at the UK home automation site for lots of info.
A bit more fun if you are a gadget freak or a tinkerer is Electric Imp - started by a guy from google and the guy who designed most of the iPhone hardware (as well as designing the best car stereo ever - even now 15 years later) - this device lets you make any device in your house Internet controllable :-)
