WNN meaning in Community ?

World News Now (or WNN) is an American overnight news broadcasting that is broadcast on ABC. Airing during the early morning hours each Monday through Friday, the program features a mix of general news and off-beat stories, along with weather forecasts, sports highlights, feature segments, and repurposed segments and story packages from other ABC News programs; its tone is often lighthearted, irreverent and humorous.

Created by David Bohrman, who also served as the original executive producer, a number of well-known news personalities have anchored WNN early in their careers, including original anchors Aaron Brown and Lisa McRee, Thalia Assuras, Kevin Newman, Alison Stewart, Liz Cho, Anderson Cooper and current ABC World News Tonight anchor David Muir. The program is primarily co-anchored by ABC News correspondents Kenneth Moton and Mona Kosar Abdi, who also anchor the network's early-morning news program America This Morning.

WNN is divided into four segment blocks ("A", "B" "C" and "D") that start with national and international news headlines incorporating some pre-taped reports (with some live wraparounds) from ABC NewsOne correspondents or repeated reports from the network's evening news program ABC World News Tonight. The "A"-block also features a national weather forecast (significant weather stories are also reported during the broadcast through analysis from meteorologists employed with AccuWeather, which provides forecasts for ABC's owned-and-operated stations) and an often humorous "kicker" story that ends the block. The "B," "C" and "D" blocks usually feature a mix of stories from Nightline or the BBC, or other live-to-tape or pre-taped segments produced in-studio, depending on the day of the week.
