is an impressive amount of data, equivalent to hundreds of full-length movies or millions of digital photos. Typical households would need years to see that much data flow through their home networks. On popular Internet sites, though, the traffic (and the cost of supporting that traffic) adds up much, much faster.
Besides movies, digital still photos are one of the primary sources of big data on the Web. Google has been working for the past several years on technology designed to save network bandwidth used in transferring photos by reducing the amount of data needed to store each picture. Google is now claiming their WebP image file format is saving terabytes of bandwidth on their networks every day - an impressive accomplishment.

Recent reports from the Wall Street Journal and other sources indicate U.S. sports content provider ESPN is interested in subsidizing the cost of Internet for people who use its services. The idea is to help folks watching videos on mobile devices from incurring high charges on their data plans. Critics are immediately raising concerns over net neutrality
- free access to information and uniform policies for managing the bandwidth of applications - that has been actively debated for many years.

British Telecom is the latest service provider looking to roll out IP address
sharing technology to its customers. Similar to how home networks use routers
to hide and manage a group of private addresses behind one public one, Internet providers can also implement address translation on their servers to route multiple customers through one shared IP number. Unfortunately, this technology when enabled often interferes with the functioning of some important Internet applications. For example:
- remote access applications may not be able to connect to your home network
- online gaming sessions (including those over Xbox Live or PlayStation Network) may fail
- it may not be possible to share files with others on peer-to-peer (P2P) networks
Note that providers could avoid these IP sharing hack if they simply upgraded their networks to IPv6.

Many software and services companies are always looking for new and interesting ways to promote their technology. The folks at Microsoft and T-Mobile think they've found a good one: Making a disposable wireless Internet router
and embedding it into full page magazine adds for office software. You can get your copy in the May 6th (2013) edition of Fortune magazine.
What's the catch? The router only connects to T-Mobile's Internet service and works free for only 15 days. After that, a person must add a paid T-Mobile subscription for the device, or find a way to dispose of the router. Being disposable, though, this shouldn't be much of a problem.
Would you buy the magazine just for 15 days of free hotspot access?
And, what will these people think of next??
