Sporty Facebook acquires a San Francisco-based startup

Facebook has acquired SportStream, a San Francisco-based startup that analyzes mentions of sports on social media sites like Twitter, Facebook and Instagram and provides clean data access to news outlets, media sites and sports teams. SportStream provides real-time data around major sporting events, and Facebook will use this data to help news organizations, including sports teams. The acquisition will help Facebook capture the real-time discussion around sports, something that Twitter still excels in.

Yahoo acquires a small California-based startup PeerCDN

PeerCDN’s technology delivers website’s static assets (like images, streaming videos, and file downloads) over a peer-to-peer network made up of the visitors currently on website. Popular files on website can be quickly and cheaply delivered via a peer-to-peer network of people currently visiting a website , while rarely-visited content can be served reliably from normal web servers. PeerCDN’s technology is using WebRTC, real-time communication technology, instead of using an additional software.

Yahoo has acquired content delivery network provider PeerCDN in a bid to resolve its e-mail service and Flickr. Yahoo has been hit with embarrassing outages of its e-mail service and Flickr, so the appeal of a service like PeerCDN — which promises to reduce web crashes — is obvious. PeerCDN could also be very useful with native Yahoo audio/video content.

Another billion dollar acquisition in silicon valley, Google is set to acquire Waze for $1.3 Billion

Recently Yahoo has bought Tumblr For $1.1 Billion, now another billion dollor acquisition is set by Google. After much competition and debate, it appears Google is close to buying popular maps and traffic company Waze.

Waze is a free social GPS application as it is a community-driven application and learns from users’ driving times to provide routing and real-time traffic updates. It is also free to download and use, as it gathers map data and other information from users who use the service. Additionally, people can report accidents, traffic jams, speed traps, police and can update roads, landmarks, house numbers, etc. Waze won the Best Overall Mobile App award at the 2013 Mobile World Congress, beating Dropbox, Flipboard and others. Waze was founded in 2008 in Israel by Uri Levine, Ehud Shabtai and Amir Shinar.

In January, Apple was considering a $500 million bid for Waze, but on May 28, Apple CEO Tim Cook denied that Apple had made a bid for Waze. After that Facebook was in discussions to spend over US$ 1 billion dollars to purchase Waze until the social media giant reportedly pulled out of talks after the two parties could not come to agreement about relocating operations. Waze insisted on locating itself in Israel and Facebook wanted Waze to move to California.

Google had approached Waze after its talks with Facebook became public. The Google deal would keep Waze and its CEO, Noam Bardin, in Israel for the next three years and allow it to remain independent and retain its brand. By buying Waze, Google can keep competitors like Apple and Facebook away from such reliable and popular mapping software.
