Idle notes.

• The United States Olympic Committee has announced the launch of a new channel devoted to Olympic sports. The USON -- U.S. Olympic Network -- will launch in 2010 and feature "live coverage of championship competitions," including coverage of the Olympic Trials after 2012. As a joint venture between the USOC and Comcast, the USON will launch on Comcast's Digital Classic tier, which reaches over 10 million households.
• A U.K. version of ESPN is set to launch on August 3. The channel will be the home of ESPN's newly acquired English Premier League coverage, and will also televise U.S. sporting events previously carried by ESPN America. The new ESPN channel will use "Sky Sports’ in-house production team to produce its Premier League matches," and will also devote original studio programming to the sport.
• Nearly three months after its short-lived debut, ESPN's redesigned BottomLine has returned. The new BottomLine debuted on April 6 along with new graphics for SportsCenter, but did not even last a full day due to technical difficulties. The BottomLine made its second debut quietly on Wednesday afternoon.
