WFAA also has a Mobile DTV feed of subchannel 8.1, broadcasting at 1.83 Mbit/s.
Previously, channel 8.2 carried "News 8 Now" (formerly known as "Xpress 8.2"). It screened weather radar, regular news updates and headlines on a crawl, and occasional live programming. This live programming included ABC News Now. This subchannel could also be used for special programming, especially hurricane season, when it was used to relay WWL-TV in New Orleans for Hurricanes Katrina in 2005 and Gustav in 2008; and KHOU-TV in Houston for Hurricane Ike in 2008. Both WWL and KHOU are sister stations to WFAA. While viewing the Doppler weather radar, it broadcasts NOAA Weather Radio station KEC56 in Dallas. It also utilizes NOAA's KEC55 in Fort Worth and KXI87 in Corsicana as alternate feeds. On April 30, 2011, WFAA's secondary channel switched to AccuWeather from its previous format as News 8 Now.
Subchannel 8.3 originally carried This TV until November 8, 2010. WFAA placed the Live Well Network in the 8.3 slot the following day. On December 7, 2010, This TV was moved to KDAF on digital subchannel 33.3.

Famous quotes containing the word television:
“There was a girl who was running the traffic desk, and there was a woman who was on the overnight for radio as a producer, and my desk assistant was a woman. So when the world came to an end, we took over.”
