In 2007 and 2008, WCWN aired WRGB's 11 o'clock news during CBS' coverage of NCAA March Madness. On January 13, 2008, WRGB began producing its newscasts in high definition, becoming the first in the market to do so. This was exactly 80 years to the date after its first experimental broadcasts. The WCWN broadcast was upgraded the next day. After becoming a sister station, it was rumored that WCWN would add a WRGB-produced 10 p.m. broadcast to challenge WXXA's long time dominance at that hour. This became a reality on September 24 when WRGB launched a weeknight 10-minute block in high definition featuring the top stories of the day along with an updated weather forecast. Accordingly, it was known as "The CBS 6 News 10 at 10". The success of the 10-minute newscast resulted in the expansion to a full 30 minute newscast in October 2010, currently anchored by Dori Marlin and Jerry Gretzinger.
