It's obvious. California is the gateway to/from Asia. Everything comes through the port from the freighters, and then gets distributed throughout the country. As far as IT, it is all about attracting the top talent, and that is why Facebook and Google has lounges, gyms, yoga classes, etc. It is much easier to attract someone to come to California where the weather is great, and have a huge variety in culture. It appeals to the talent, their family, and parents. Taxes are high, but these guys make a ton of money, so the standard of living is already high. California is great when you can afford it.
