Editor’s note: This is the fourth in a series of posts by guest writer Ashkan Karbasfrooshan
.Previously, he wrote about the State of Online Video, 12 Surprising Things Holding Back Online Video Advertising, and Context is King: How Videos Are Found And Consumed Online. In part 4 today, he examines where he thinks the sweet spot is for making money in onljne video. Karbasfrooshan is the founder and CEO of WatchMojo.
In Search of Profits
Ten years ago, web companies didn’t generate much revenue. These days, web companies are some of the most profitable around. Online video is where the Web was ten years ago: in investment mode as video companies that are generating high revenue are not necessarily the most profitable.
Are those companies suffering low margins because they’re investing in the future or are they fundamentally lower-margin businesses?
Ad Networks Are Low Margin Businesses
This week, video ad network Brightroll raised $10 million from Scale Venture Partners. Ad networks aggregate audiences and sell ads to marketers, sharing the proceeds with publishers/producers. Scale’s Rob Theis’ argues: “the most strategic Internet investments are those that compete not with other Internet businesses, but with the much larger amount of money still being spent offline.”
Brightroll’s CEO Tod Sacerdoti added: “I think by this time next year the majority of the top five to ten video properties by any measure will be aggregator networks. The best example for this is display advertising.” Indeed, networks have an unmatched ability to scale but can also crash to the ground awfully fast.
The low margin is the least of their problems; differentiation and defensibility are. Blue Lithium and Right Media hit jackpots by selling to Yahoo! But those who didn’t sell (Tribal Fusion, Valueclick) suddenly found themselves under pressure from search advertising on performance and video on branding.
Content Networks Have Little Differentiation
Similarly, aggregators gather videos from content providers, sharing ad revenues. iFilm (sold to Viacom, renamed Spike), Guba, Grouper (sold to SONY, renamed Crackle), Revver, YouTube (sold to Google), Veoh, DailyMotion, Metacafe, Viddler, blip.tv, are all vying for content, audiences and dollars.
YouTube is master of this domain. Hulu is giving YouTube a run for its money, but the business model is anything but certain and its long term exit strategy is murky (Disney, News Corp. and NBC Universal/Comcast are shareholders but also competitors).
Ultimately, ad and content networks operate in a high-risk, winner-take-all game. For publishers, it’s a lower risk world. Consider the two acquisitions News Corp. made in 2005: Rupert Murdoch paid more for IGN ($650M) than for MySpace ($580 million), but MySpace’s subsequent growth made him look like a genius (for a while). Today, MySpace is searching for its raison d’etre while IGN treks along as an unstoppable force in its sphere.
The Myth of Hyper Distribution?
In online video, producers are agnostic to distribution channel or platform. To reduce risk, they diversify distribution, but the jury’s out on whether hyper distribution bears fruit. Hyper distribution refers to syndicating one’s content as broadly as possible with little or no restrictions.
When it comes to generating revenues, is hyper-distribution wise? Not according to Chris Pirillo, a prosumer video producer who leverages video to promote his empire but only counts YouTube as a commercial platform: “YouTube offers the largest audiences and generates most the revenue. If you’re not YouTube, you have challenges in creating value for content producers”. If that changes, look out for Freewheel, which according to CEO Doug Knopper allows “media companies and content owners to be able to monetize their video libraries across multiple channels and devices”.
Advertisers Follow Audiences…
Ex-Disney CEO Michael Eisner doesn’t pretend to know how the industry is going to play out, but he’s got no doubts what the end result will be: “I don’t know if the growth in content made for the Internet will be evolutionary or revolutionary, but it can’t not happen: a death march has been going on for other media who are in trouble because there is a more efficient way to share content around the world with the Internet.”
Business Models Take Time to Develop
Eisner made his fortune in television. One VC who’s made his online has another opinion. In Fred Wilson’s influential 2005 post “The Future of Media (aka Please Take My RSS Feed)”, he suggests to:
1 – Microchunk it – Reduce the content to its simplest form.
2 – Free it – Put it out there without walls around it or strings on it.
3 – Syndicate it – Let anyone take it and run with it.
4 – Monetize it – Put the monetization and tracking systems into the microchunk.
In theory, in the future when video streams monetize the way search queries have (whereby a search query is always associated with some kind of paid listing) then perhaps Wilson’s thesis will prove right. But in practice, at least in the five years that have passed since the post, it’s been a recipe for financial disaster.
Hyper distribution is great for promotional purposes but not necessarily for commercial purposes. Marketers do pay more attention as an audience grows, but they also pay a premium for scarcity and exclusivity.
This is the fundamental conundrum facing new media producers who rely on hyper-distribution to build brands and audiences but who weaken their pricing power and ability to secure guaranteed dollars by giving away their videos. This can work if you can build ad-supported businesses, but that takes time and money.
Today, a few new media producers have managed to build ad-supported businesses, namely Revision3 and Next New Networks. But between the two, they have raised over $30 million in venture capital. Most producers don’t have that luxury. For those others, I recommend creating content that other media companies will pay for, to buy them enough time to build a syndication business and eventually, a fully ad-supported business which commands the large ad dollars.
An imperfect but useful analogy I use is the banking model, where retail, corporate and investment banking fees can create a large business.

YOUGOTNOPROOF~~
带绿十字的就是网络上的Tor结点,正是这些Tor结点才使得你的访问可以进行,而当其中某一个结点不可用时,程序会自动进行处理,确保你的访问正常进行,如图:
从而我们可以通过Tor的网络访问【目标服务器】而不是通过平时的网络,而Tor网络传输又是高度加密的。
3)配套组件Vidalia
简单来说,Vidalia就是将Tor的Dos窗口转化为更人性化的图形操作界面,便于用户管理和操作。
关于Autoproxy
1)Autoproxy是什么?
autoproxy是一个Firefox的扩展组件,派生自 Adblock Plus,能自动、高效地管理代理。autoproxy会自动识别并告诉你的翻墙工具,哪些网站需要使用代理,而其它的网站直接连接。当然,前提是你订阅了gfwlistf代理规则。
2)gfwlistf是什么?
gfwlistf是由一群志愿者精心维护的一个被GFW屏蔽的网站列表。订阅之后,会自动更新。记录在册的网站会自动走代理出去。
安装与使用
1)下载并安装Firefox
Firefox浏览器官方网站:http://www.mozillaonline.com/
注:如果你现在用的是Firefox浏览器的话,那你可以跳过此步骤。
2)下载并安装Tor+vidalia
Tor: 匿名在线官方网站:http://www.torproject.org/(已被墙)
注:考虑到官网被墙的问题,小清在这里提供Tor+vidalia安装包下载。
Tor+vidalia下载链接:rayfile免费网盘
Tor安装之后,会向Firefox提示安装Tor扩展,点击取消。因为我们有更强大的Autoproxy。
安装完vidalia并启动之后,双击并打开vidalia控制面板,可以在Settings里的Appearance下找Longuage选项,把系统文字更改为简体中文。
如果Tor没有按默认路径安装的话,需要在General里设置Tor正确路径,最上面的选项Start Vidalia when system starts决定Vidalia是否随系统开机启动。之后可以通过按钮Stop Tor可以开启或关闭Tor代理。
3)安装Autoproxy
访问https://addons.mozilla.org/zh-CN/firefox/addon/11009
在:让我安装这个试验性的附加组件 前面打上√,点击[安装到Firfox]
安装完成并重启浏览器,Autoproxy会询问是否订阅gfwList,选择并订阅。
点击Firefox右上角的福字图标,打开Autoproxy首选顶,依次打开[代理服务器]>[选择代理服务器],将默认主代理更改为Tor。
由于gfwList内置了大量被GFW屏蔽的网站列表。这个时候,Firefox基本上可以访问常规的墙外网站了。如果您发现某个网站不在此列表中,你可以打开Autoproxy首选项按增加规则添加进去即可(例如刚刚挂掉的Google.com)。
另外,如果你觉得Autoproxy的按钮过于碍眼或者占地方,可以在选项里将其显示位置更改至状态栏,或者干脆不显示
全文到此完毕,有任何翻墙或Firefox方面的问题或意见、建议请跟帖,小清会尽我所能为您解答。如果你翻墙成功了,也记得顶一下帖子哦!
tor打不开的,看这里:http://blog.yeefe.com/wangxiaofei/?p=1902
请按下述方法进行操作:
发送邮件至bridges@torproject.org,正文为“get bridges ”(不含引号,邮件可以不写主题)。几秒钟之内,你会收到回信(你必须使用Gmail邮箱,否则不会收到回复),信件内容如下(举例):
现在,打开Vidlia控制面板的 [ 设定 ] 菜单,切到 [ 网络 ] 选项,勾选 [ 我的ISP阻挡了对Tor网络的连接 ] 。将回信中的地址拷贝粘贴至在 [ 添加一个网桥 ] 下方空白栏内,然后点击右边绿色加号按钮进行添加,如下图:
完成之后点击 [ 确定 ] ,并重新启动Tor便能正常连接。
