How websites like Google have access to stock market data? 
To quote their disclaimer: Data is provided by financial exchanges and may be delayed as specified by financial exchanges or our data providers. Google does not verify any data and disclaims any obligation to do so. That means that they buy it from a reseller such as IDC. It probably differs in source between the different exchanges depending on price and availability factors. They do specify in some cases which reseller they use and one of those happens to be Interactive Data (IDC) who are also the data provider used in my day job!
