WNDU-TV (channel 16) is a television station in South Bend, Indiana, United States, affiliated with NBC.

However, like its radio sisters, it operated as a full-fledged commercial station rather than a non-profit public broadcaster (which is standard, and much like fellow NBC affiliate KOMU-TV in Columbia, Missouri, was and still is; after WNDU-TV was sold, this left KOMU and WVUA-CD/WVUA in Tuscaloosa, Alabama, as the only commercial TV stations owned by a university).

WNDU-TV's early broadcast schedule included programs like Romper Room and the first local telecast of a Notre Dame football game.

[6] The sale closed on March 5, 2006, after which the Federal Communications Commission granted Gray a cross-ownership waiver for WNDU and Goshen-based newspaper The Goshen News.

[15] On February 1, 2021, Gray Television announced its intent to purchase Quincy Media, owner of Heroes & Icons affiliate WSJV, for $925 million in a cash transaction.

In addition, the station's primary channel preempts the Saturday edition of Today for its Saturday morning newscast with the program airing on its second digital subchannel instead; the primary channel airs the Sunday edition of Today on a one-hour delay in order to accommodate its Sunday morning newscast.

Prior to its move to Peacock on September 12, 2022, WNDU aired the soap opera Days of Our Lives one hour later than most NBC affiliates at 2 p.m. local time.

Under Notre Dame's ownership, WNDU opted not to air certain NBC programs out of concerns over inappropriate content.

[22] The station's signal is multiplexed: WNDU's second digital subchannel formerly carried a standard-definition simulcast of the station's main channel (with limited programming substitutions for shows preempted on the main channel for local programming); the subchannel became affiliated with Antenna TV on July 1, 2013.

As part of the SAFER Act,[27][better source needed] WNDU-TV kept its analog signal on the air until March 3 at 7 p.m. to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters.
