Our product development philosophy is centered on rapid and continuous innovation, with frequent releases of early stage products that we seek to improve with every iteration. We often make products available early in their development stages by posting them on Google Labs, at test locations online or directly on Google.com. If our users find a product useful, we promote it to "beta" status for additional testing. Once we're satisfied that a product is of high quality and utility, we remove the beta label and make it a core Google product.
