On April 21, Urchin (now called Google Analytics) celebrated its 5th anniversary. “on April 21, 2005, Google acquired Urchin Software Corporation. At the time, we had no idea how popular Google Analytics would become. To a great extent, Google Analytics' popularity is a reflection of the phenomenal accomplishments and hard work of many talented and passionate people here at Google. But mostly it is you, our customers, who have made the product what it is today. You've requested features, provided feedback, and asked tough questions. We're humbled and thankful. And, we're excited for the next 5 years. Congratulations and happy anniversary!,” posted Google.
