Just for Thoughts Why Microsoft buy Skype for US$8.5 billion? Microsoft already has its own software comparable to Skype - Windows Live Messenger, which offers free instant messaging, and voice- and video-chat. Windows Live Messenger Ø 330 million active users/ mth. Ø 40 million online users at any one moment. Skype Ø 124 million active users/ mth. Ø 20-30 million online users at any one moment. Ø Free of charge. Ø About 8 million Skype users pay for the service Ø Does not offer phone services Ø Telephony infrastructure - Able to make both outbound and inbound phone calls.

Possibilities of Microsoft s Acquisition Ø User base. Microsoft hopes to sell other products to Skype's huge user base -- more than 660 million users, including more than 120 million active or "connected" users. Ø Peer to peer video. Lync has one-to-many videoconferencing, but Skype's peer-topeer video chat adds another potentially more efficient and easier way to place video calls. Competitors- Cisco and Google. Ø Rumors of other companies' interest. Microsoft made a fairly generous offer back in April -- over the $7 billion that Skype insisted on as a starting point -- because it had heard rumors that other companies like Cisco, Google, and Facebook were interested in Skype as well. Ø Windows Phone 7 (Mobile OS) and Nokia. The software giant needs a competitive offering to Google Voice and Apple s emerging communication platform, Facetime. Ø Microsoft is an investor in Facebook : It gets access to Skype assets and it gets to keep Skype away from Google.

The Deal.. Ø ebay gets $2.55 billion for its 30% stake in Skype. Ø Niklas Zennström and Janus Friis, the cofounders, with their 14% stake, take home about $1.19 billion. Ø Silver Lake, Andreessen Horowitz and the Canada Pension Plan Investment Board (CPPIB) own 56% of the company, and that stake is worth $4.76 billion. Ø Andreessen Horowitz had 3% of the deal and made $205 million profit on their $50 million initial investment.

After the acquisition Skype announced two new versions of its product on 17 Nov 2011: Skype 5.4 Beta for Mac and Skype 5.7 Beta for Windows. Ø Include Facebook integrations that essentially add your Facebook friends to your Skype contact list. Ø Users who connect their Facebook profiles can make video calls from within Skype to friends who will answer using Facebook. Ø Able to see Skype s dashboard when Facebook friends are online, read their status updates and IM them
