WNDY-TV (channel 23) is a television station licensed to Marion, Indiana, United States, serving the Indianapolis area as an affiliate of MyNetworkTV.

Founded by G. J. Robinson, it originally operated as an independent station; it ran mostly paid programming, but slowly added classic sitcoms, cartoons and older movies.

Spartan Communications – which planned on turning over WNDY's operations to Fox affiliate WXIN (channel 59) under a local marketing agreement with Tribune Broadcasting – agreed to acquire the station in August 1997,[7] only to back out of the deal an hour before it was scheduled to be finalized on October 3.

[21] On October 2, 2008, cable provider Bright House Networks pulled WISH-TV, WNDY and WIIH-CA from its Indianapolis area system as it and LIN had been unable to reach a new agreement for the stations regarding compensation for their carriage.

[26][27][28][29][30] However, on September 28, Irving, Texas–based Nexstar Broadcasting Group made an unsolicited cash-and-stock merger offer for Media General, originally valued at $14.50 per share.

[31] On November 16, following opposition to the merger with Meredith by minority shareholders Oppenheimer Holdings and Starboard Capital (primarily because Meredith's magazine properties were included in the deal, which would have re-entered Media General into publishing after it sold its newspapers to BH Media in 2012 to reduce debt) and the rejection of Nexstar's initial offer by company management, Media General agreed to enter into negotiations with Nexstar on a suitable counter deal, while the Meredith merger proposal remained active; the two eventually concluded negotiations on January 6, 2016, reaching a merger agreement for valued at $17.14 per share (an evaluation of $4.6 billion, plus the assumption of $2.3 billion debt).

WNDY carried the Saturday edition of CBS This Morning, with the last broadcast on December 27, 2014, and the weekend editions of the CBS Evening News and the second half-hour of Face the Nation both ending on December 28, 2014, in lieu of WISH-TV (in the case of the former two programs, WISH declined to air them in order to run expanded Saturday morning and weekend 6 p.m. newscasts).

[48] WNDY occasionally aired Indianapolis Colts games that are televised on ESPN's Monday Night Football, as NFL regulations require games that air on one of the league's cable partners to be simulcast on a broadcast television station in each participating team's home market (the station had been carrying ESPN's Colts game telecasts since it held rights to the Sunday Night Football package, which it lost to NBC in 2006, when ESPN took over rights to Monday Night Football).

One notable exception to this occurred in October 2013, when WTHR (channel 13) carried an ESPN-televised Monday night game involving the Colts.

[49] The station also aired select Ball State University men's basketball games as well as Mid-American Conference college football from ESPN Plus.

The deal for carriage of the games in Indianapolis was required after Tribune Media discontinued airing Chicago area sports over WGN America at the end of 2014.

[51] In early 1996, NBC affiliate WTHR entered into a news share agreement with WNDY to produce a nightly half-hour primetime newscast at 10 p.m. for the station, titled Eyewitness News at 10:00 on Indy TV (the title later being revised slightly to correspond with WNDY's branding changes to "UPN 23" in 1998 and "UPN Indiana" in 2002), which debuted on March 16 of that year.

The WNDY newscast briefly gained another competitor on that date when WTHR moved the Eyewitness News at 10:00 broadcast to sister station WALV-CD (channel 46); that program was subsequently moved to Pax TV owned-and-operated station WIPX-TV (channel 63, now an Ion Television O&O) on April 13, 2005, before being cancelled two months later on June 30.

The station's signal is multiplexed: WNDY formerly carried TheCoolTV on its second digital subchannel from 2010 to 2013, when LIN Media terminated its affiliation agreement with the music video network.
