Sangean intros WFR-20 tabletop WiFi radio - Engadget
It's been nearly a year since we've heard from Sangean, but the company is hitting back with a swank new WiFi internet radio that's shaped a good deal like its past units. The WFR-20 offers up 'direct access to over 6,000 Internet Radio stations (and 21,242 on-demand streams) in 250 locations from 60 genres,' and you can organize your favorites in the My Stations folder. Additionally, it's designed to operate with or without a PC, and if you have a networked computer nearby with Windows Media Player, you can have 'full access to your digital media library using the UPnP Server.' Furthermore, you'll find a three-line display, four alarms, an aux input, dual five-watt speakers, and a wireless remote to boot, but there's no word on a price or release date just yet.

An example of standards organizations being used:
"If This Was a Month Ago, OOXML Would Be Over Posted by ScuttleMonkey on Monday September 03, @06:28PM from the games-of-corporate-chess dept. Microsoft Andy Updegrove writes 'Public announcements of how Participating members of ISO have voted on OOXML are now rolling in one at a time, and the trend thus far is meaningfully weighted towards 'No with comments.' By my count, there are now four announced Yes votes, with comments, two abstentions, and seven public No with comments votes for OOXML in ISO/IEC JT1. Korea has reportedly voted no as well, and I expect at least Canada, Japan and the United Kingdom to announce 'No with comments' today or tomorrow. There will be more no votes on the roster when the final results are announced in a day or two. But even if the 11 votes I know of now were the only votes, the vote would now have failed — but for the 11 countries that upgraded their status from Observer to Participating member status in the last few weeks. Without those extra 11 'P' countries, it would only require 10 votes to block OOXML from immediate approval. If most or all of those additional 'P' members vote 'yes' as expected, it will confirm suspicions that Microsoft has promoted extra votes in favor of OOXML not only within National Bodies, but within ISO itself.'"

- International Organization for Standardization (ISO): Probably the biggest standards organization in the world, the ISO is really a federation of standards organizations from dozens of nations. In the networking world, the ISO is best known for its OSI Reference Model.
- American National Standards Institute (ANSI): ANSI is the main organization responsible for coordinating and publishing computer and information technology standards in the United States. While they are commonly thought of as developing and maintaining standards, they do neither. Instead, they oversee and accredit the organizations that actually create the standards, qualifying them as Standards Developing Organizations or SDOs. ANSI also publishes the standards documents created by the SDOs, and serves as the United States' representative to the ISO.
- Information Technology Industry Council (ITIC): ITIC is a group of several dozen companies in the information technology (computer) industry. ITIC is the SDO approved by ANSI to develop and process standards related to many computer-related topics. It was formerly known as the Computer and Business Equipment Manufacturers Association (CBEMA).
- Institute of Electrical and Electronics Engineers (IEEE): The IEEE (pronounced “eye-triple-ee”) is a well-known professional organization for those in the electrical or electronics fields, including computers and networking. IEEE's main claim to fame in the networking industry is the IEEE 802 Project, which encompasses many popular networking technologies including Ethernet.
- Electronic Industries Alliance (EIA): The EIA is an international industry association that is best known for publishing electrical wiring and transmission standards.
