最早的时候，谷歌搜索的网址是挂在斯坦福大学的网站上的。谷歌的创始人拉里·佩奇和谢尔盖·布林在1997年发表的论文中说：
“我们认为由广告商来赞助搜索引擎，将会使得搜索引擎的返回结果受到广告商的需求的影响，从而偏离真正的用户需求。广告越多，搜索引擎的搜索质量就越差。正因为广告商的存在会极大影响搜索引擎的质量，我们相信我们的社会需要一个搜索质量优秀、排序公正透明、由学术界监督的搜索引擎。” source

Telegram has exploded as a hub for cybercriminals looking to buy, sell and share stolen data and hacking tools, new research shows, as the messaging app emerges as an alternative to the dark web.An investigation by cyber intelligence group Cyberint, together with the Financial Times, found a ballooning network of hackers sharing data leaks on the popular messaging platform, sometimes in channels with tens of thousands of subscribers, lured by its ease of use and light-touch moderation.
Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
