We’re on the cusp of a global conflict that will see the three
 most powerful consumer Internet companies fighting to win control of 
interpersonal communication. The war will pit Facebook’s unified Chat / 
Messages / Email vs Apple’s cross-device iMessage system vs. Google’s 
Gmail / GChat / Hangouts. If one emerges as the definitive victor, it 
could sway the future of digital human interaction.
Read on as we survey the battlefield, review the weaponry of each 
company, and assess who could win the epic message war and the fortune 
that comes with it.
Last week we saw 
Facebook fire the shot of this war when
 it changed everyone’s profile contact info to display their 
@facebook.com address and hide their previously selected Gmail, 
MobileMe, or other email addresses. Why? To box out Google and 
Apple. Even with natural advantages like a firm grip on identity and the
 social graph, plus the fact that it works across both iOS and Android 
devices, Facebook still felt like it needed to attack.
We’ve likely reached “peak SMS” — next year fewer text messages may 
be sent than this year due to the rise of data-based alternatives. Now 
is the time for one of these three messaging platforms to take the place
 of SMS.
Preparing For Battle
Over the last few years, the three combatants have been scrambling to
 arm themselves for the coming message war. Movement has sped up over 
the last few weeks, though, indicating we could soon start seeing peace 
treaties broken and heavier assaults launched.
Facebook
In November 2010, Facebook 
unified its messaging platform
 so instant Chats, asynchronous Messages, and email sent to the newly 
offered @facebook.com addresses would all flow into one inbox. In some 
ways this was great for users because if someone sent you a Chat and you
 were offline or immediately left your desktop, you could view it in 
your Messages inbox from mobile.
Similarly, if you sent someone a message but they were currently 
online, it’d get delivered as a chat. You could voluntarily set up a 
Facebook email address, but few people did and that wing of the service 
stalled. Then in April, 
Facebook began assigning email addresses to everyone.

July 2011 saw a 
partnership with Microsoft’s Skype that allowed Facebook to add video chat capability to its platform. It also 
acquired and re-skinned Beluga as Facebook Messenger in August 2011 as a standalone app to break direct communication out from its bloated primary app. 
Facebook Messenger doesn’t do voice or video just yet but you can bet it’s on the way.
In Facebook’s arsenal are the world’s largest social graph, mobile’s 
most popular apps, massive time-on-site across devices, a deep 
understanding of who we’re closest to, and a thriving ad platform to 
monetize it all with.
Identity is key to messaging because it lets people connect just by 
name, allowing the best communication medium for the job be selected as 
the specific contact information falls into the background. It does not 
own the hardware or the OS, but it can float as a layer across devices 
which is why Facebook may have the most powerful war machine.
Google

Meanwhile,
 Gmail continued gaining popularity while Gchat (formally named Google 
Talk) became a preferred instant messaging system for professionals who 
thought themselves too mature for AOL instant Messenger or IRC, and 
didn’t want to be frequently interrupted with small talk chats from 
distant Facebook friends. In September 2010, Google acquired 
group-chat and organization app Plannr.
Then Google launched Google+ in June 2011 with its stand-out feature 
Hangouts, a real-time group video chat service that also offered some 
collaboration and synchronous media consumption options. It also turned 
Plannr into Google+ Messenger. Now as 
GigaOm reports
 from last week’s I/O conference, Google is merging Hangouts, Talk, and 
Messenger into a single unified messaging platform that could allow 
text, voice, and video chat across devices.
Google’s strongest asset is its diversity. It owns Android, the 
mobile OS that’s locking down the long-tail. It’s working with Samsung 
to build hardware and also owns Motorola now. It’s got a fair amount of 
cash, which can’t hurt, plus a presence in social networking that can 
tie Android and Chrome OS together. Most importantly, it controls Gmail,
 arguably the winner of the last communication war that was fought for 
email.
Apple

Apple launched iMessage in October 2011 as an SMS alternative for iOS
 devices that also sends photos and other media. iMessage will link 
desktop and laptop computers to their mobile brethren when 
Apple adds it to OS X Mountain Lion.
 It wouldn’t be surprising to see Apple integrate FaceTime directly into
 the cross-device iMessage platform, though how email could feed into it
 is less clear.
Even with mountains of cash, Apple may be the underdog. It has no social network, and in fact relies on 
Facebook to bring social to iOS
 and the App Store. It could control messaging to some extent for all of
 its device users. But not everyone can afford them, and that means its 
users won’t always be able to contact friends through iMessage.
The Spoils Of War
So by next month, Facebook, Google, and Apple will each have their 
own robust messaging platforms featuring some combination of support for
 cross-desktop and -mobile communication; real-time chat with text, 
photos, voice, and video, syndication to email, and SMS delivery as a 
backup. Whichever of these features they don’t have, they’ll likely buy 
or build.
Everyone else in the messaging space, like 
Microsoft’s GroupMe and all the free SMS startups should prepare to pivot or sell to one of the three warring factions. You’re not gonna win.
What’s at stake is the control of perhaps the most critical stream of
 them all — direct communication. Content is surely important, 
especially because it creates massive engagement and time on site that 
creates a host for advertising. The ambient intimacy of Facebook, 
Google+, and Twitter let us feel closer to a huge number of distant 
acquaintances and thought leaders through the indirect communication 
of content feeds.
People love content, but people need direct communication. Who you 
communicate with on a daily basis and via what medium are vital signals 
regarding where people sit in your social graph. Whichever company owns 
the most of this data will have better ways to refine the relevance of 
their content streams, showing you updates by the people you care about 
aka communicate with most, and showing ads nearby.
Through natural language processing and analysis, whoever controls 
messages will also get to machine-read all of them and target you with 
ads based on what you’re talking about.

Communication channels will likely host that advertising too, making 
the winner of this war even richer. You might not get highly obtrusive 
mobile spam straight from marketers, but their ads could be appended at 
the end of your incoming messages.
At least expect ads mixed in between or shown around your Facebook or
 Google messages, the way Gmail shows ads right above your inbox. Apple 
meanwhile would use control of communication to bolster hardware sales 
by making the latest improvements only available on its latest devices.
The stakes of the message war are huge, so these three companies will
 fight hard. They’ll spend huge sums, form alliances if they have to, 
and make aggressive moves that could endanger the user experience to 
win. We’re already seeing it happen. And if one company does come to 
rule messaging, it could reduce the impetus for innovation and permit 
abuse. I like to think these companies are better than that, but some 
argue “whoever wins, we lose”.
Update: To clarify, “winning” this war could mean 
controlling the bulk of the market share, not necessarily 100% of it. 
There will likely continue to be scrappy startup alternatives, even one 
that 
disrupts this whole war, and none of the big guys here will totally give up if they “lose”.
But a disrupter would likely have to turn down huge acquisitions 
bids. And if the big messaging platforms don’t talk to each other and 
one gains an obvious lead (and I think one will), network effect will 
kick in, that “winner” will continue to grow its share, and it will 
dominate messaging.
Fire The Missiles
Facebook knew it was going to take a 
major PR hit for 
hiding the real email addresses and replacing them
 with its own @facebook.com addresses on the profile contact info of 
every user. The change could have been done more subtly with a slow roll
 out or with some token, quickly-sped-past notification to users.
Facebook got a late start on email, especially compared to Google, 
and many users haven’t changed their email contact info since Facebook 
launched its addresses. It needed to increase awareness about 
@facebook.com addresses, and it didn’t want @gmail.com and Apple @me.com
 addresses on everyone’s profiles. Making the change without notifying 
users was certainly bad for the user experience, but Facebook did it 
anyway.

So what will Google and Apple do to retaliate? Google could prevent 
people from listing their Facebook profiles in their G+ About sections, 
and that won’t do much damage. It could compete with Facebook Messenger 
by pre-installing its own unified messenger app in the place of a 
standard SMS app on Android devices, and integrating that app with 
Chrome OS. Apple could refuse to integrate 
Facebook any deeper into iOS, or scale back Facebook’s presence and double-down with Twitter.
Those probably won’t be enough to deter Facebook, though, and it could go on to win the message war or at least dominate it.
The Aftermath
Apple may very well foresee its coming loss or at least a prolonged 
battle. It and Facebook are relatively complementary, while both are 
fighting fiercely with Google on several fronts. So rather than pour 
resources into a losing battle, Apple might find some way to play nice 
with Facebook.
This could come through a bridge between iMessage and Facebook’s 
messaging platform. The ability to iMessage Facebook friends you don’t 
have the phone number of could increase the Apple product’s worth, and 
give iOS users a way to message with their Android-toting friends.
Mark Zuckerberg probably calculated the risk of Facebook’s aggressive
 change to visible contact info, and assumed his site could swallow lost
 trust from a few million angry tech news readers. It’s still THE social
 network, and a few days of complaints won’t change that. This isn’t 
friendly competition. It’s the war for messaging, and wars have 
casualties.
