Adobe [has shut down its BrowserLab service, used by many for testing content across multiple desktop platforms. The company pointed its customers to two alternatives: [URL="http://www.browserstack.com/"]BrowserStack and [URL="https://saucelabs.com/"]Sauce Labs](http://thenextweb.com/dd/2013/03/13/adobe-shuts-down-desktop-browser-testing-service-browserlab-without-warning-blames-rise-of-mobile-devices/). BrowserLab offered cross-browser testing by producing screenshots of websites from various browsers across Windows and OS X platforms. It was very useful for developers looking to support as many different users as possible.
Basically, Adobe never updated BrowserLab to include mobile browsers, and thus saw a drastic decline in use.
So instead of including mobile browsers, they shut the whole thing down?
