NEW YORK — The parent companies of NBC and YouTube settled a dispute that allows the network back on the online platform. YouTube blacked out NBC on Tuesday when carriage negotiations broke down. Affected in the one -day hiatus was local news on NBC affiliates nationwide. These included:

> Iowa: KWWL, Cedar Falls; KTUV, Sioux City.

> Minnesota: KTTC, Rochester; KMNF, Mankato; KARE, Minneapolis.

> Wisconsin: WEAU, Eau Claire; WMTV, Madison.

The affiliate signals were unaffected  on over-air channels, cable and other platforms during the blackout. Justin Connolly, a YouTube executive, said the new NBC deal deal represents “the evolving media landscape.” About 10 million U.S. households are equipped  with NBC access to NBC through YouTube.
