Number of google pages hits as a function of time

In ea开发者_如何学Cch search in Google one can see number of google pages found. Is it possible to find what was this number in the past?

Best what you can try is Google Zeitgeist. It doesn't give amount of found pages, but it gives insights of popularity of keywords, example: "stackoverflow". You can also check the popularity of a website, example: stackoverflow.com.

No other Google services comes to mind for your particular purpose.

No this number is not available. You could run the query and parse the Google results to capture the information, but I read the terms of use before you try to do that. In most case it will be against the terms of usage to do something like that.
