????驅動因素之三：市場廣闊

????如今的高科技公司瞄準的是巨大的市場，它們的規模令前幾代科技公司相形見絀。簡而言之，如今成功科技公司的前景比過去要廣闊得多，因為它們面對的終端用戶市場極為廣闊。

????原因何在？我的合伙人馬克?安德森經常提到的數據很能說明問題。安德森1998年將自己創辦的網景公司（Netscape）出售給了美國在線（AOL）。彼時，瀏覽器市場的用戶總數約5500萬，幾乎所有人都是通過撥號上網。

????而如今，隨著寬帶的普及以及智能手機和平板電腦的發展，有25億人幾乎隨時都能聯網。而且這個人數很快將超過50億。

????這樣看來，1999至2000年泡沫期間的互聯網公司紛紛倒閉也就不足為奇了。說到底，這些公司面向的市場太小了，而獲取新用戶以及為新用戶提供技術基礎設施的成本過高（還記得那會兒Sun公司售價高達5萬美元的服務器么？）。

????相比之下，如今不僅終端用戶市場要大得多，而且支撐這些市場所需的技術成本要低得多【比如亞馬遜網絡服務（Amazon Web Services）、開源軟件組件等】。規模經濟終于發揮效力了。

????當然，不是每家在大學宿舍中搗鼓出的高科技公司都能像Facebook那樣大獲成功。也不是說風險投資家和公眾投資者不可能失去理智，盲目地將所有網絡公司的市盈率都炒到15到20倍。

????泡沫當然有可能出現。但現在還沒有。（財富中文網）

????Driver No. 3: These are massive markets

????Today's technology companies are going after massive markets, the value of which dwarfs that of previous generations of tech companies. Simply put, the winners in tech today can become massively larger than the winners of yesteryear because the end-user markets into which they can sell are enormous.

????Why is that? My partner, Marc Andreessen, likes to recount a simple stat that sums it up quite nicely. When his company Netscape was sold to AOL (AOL) in 1998, the total size of the browser market was roughly 55 million users, nearly all were accessing the Internet via those ear-screeching dial-up connections.

????Fast-forward to today, largely as a result of broadband penetration and the growth of smartphones and tablets, and there are 2.5 billion people with virtually ubiquitous Internet access. And that number is likely to exceed 5 billion in short order.

????Is it really any wonder then why so many of the 1999-2000 bubble-era Internet companies failed? The markets into which they were selling were simply too small compared with both the costs of acquiring customers and the costs of the technology infrastructure (remember that $50,000 box called a Sun server?) required to support these customers.

????By contrast, not only are the end-user markets today vastly bigger, but the technology costs required to support these markets (think Amazon Web Services (AMZN), open source software components, etc … ) have plummeted. The economics finally work.

????This isn't to say that every new technology company being incubated at a university dorm will achieve the success and scale of Facebook. Nor is it to say that venture capitalists and public investors may not ultimately lose their minds and blindly pay 15 to 20 times revenue multiples for any dotcom company.

????Bubbles can, of course, happen. But we simply aren't there yet.
