While many of the larger cable companies have been expanding their HD lineups of late, we figured the little guys should get their time in the spotlight, too. According to a tipster parked in the Metro Detroit area, four new high-definition channels have been added to Wide Open West (or WOW!, as it were). Effectively immediately, customers in the region can look forward to Discovery HD on channel 225 (HD Theater relocated to 210), Animal Planet HD on 226, TLC HD on 227 and National Geographic HD on 228. Any WOW! subscribers in other locations receive the updates, too?
