WMAQ-TV, channel 5, is an owned-and-operated television station of the NBC Television Network, located in Chicago, Illinois, USA. WMAQ-TV's main studios and offices are located within the NBC Tower in the Streeterville neighborhood, with an auxiliary street-level studio on the Magnificent Mile, and its transmitter is atop the Willis Tower. WMAQ-TV is a sister station to WSNS-TV (channel 44), affiliated with the Spanish-language network Telemundo; and Comcast SportsNet Chicago.

See also WMAQ (AM) for pre-1948 history of the station.

The station signed on October 8, 1948, as WNBQ, the last of Chicago's four commercial VHF stations to launch, and the third of the five original NBC owned-and-operated stations, three weeks ahead of WNBK (now WKYC-TV) in Cleveland. Eight years later, it became the first station in the world to broadcast all of its programs in color. Though NBC had long owned WMAQ radio (670 AM, frequency now occupied by WSCR), it did not change the TV station's call letters to WMAQ-TV until August 31, 1964. The calls of its sister radio station were initially assigned by the government, but went on to form the phrase "We Must Ask Questions," which the radio station took on as its motto in the 1920s.

A missing person is a person who has disappeared for usually unknown reasons.

Missing persons' photographs may be posted on bulletin boards, milk cartons, postcards, and websites, along with a phone number to be contacted if a sighting has been made.

People disappear for many reasons. Some individuals choose to disappear alone; most of these soon return. Reasons for non-identification may include:

By the end of 2005, there were 109,531 active missing person records according to the US Department of Justice. Children under the age of 18 account for 58,081 (53.03%) of the records and 11,868 (10.84%) were for young adults between the ages of 18 and 20.

During 2005, 834,536 entries were made into the National Crime Information Center's missing person file, which was an increase of 0.51% from the 830,325 entered in 2004. Missing Person records that were cleared or canceled during the same period totaled 844,838. The reasons for these removals include: a law enforcement agency located the subject, the individual returned home, or the record had to be removed by the entering agency due to a determination that the record is invalid.

Jerry Lindsey Martin (born May 11, 1949 in Columbia, South Carolina, U.S.) is a former Major League Baseball outfielder. He is the son of major league pitcher Barney Martin.

Martin was signed as an amateur free agent by the Philadelphia Phillies on July 17, 1971. Over the span of his 11-year career, Martin played for a total of five teams: the Philadelphia Phillies (1974–1978), the Chicago Cubs (1979–1980), the San Francisco Giants (1981), the Kansas City Royals (1982–1983), and the New York Mets (1984). The right-handed hitting Martin was almost exclusively an outfielder during his big league career.

In October 1983, Martin, along with teammates Willie Wilson, Vida Blue and Willie Aikens, was arrested and charged with attempting to purchase cocaine. All four pleaded guilty to misdemeanor drug charges and were sentenced to 180 days at a Florida minimum security prison, served time at Fort Worth, Texas, Federal Correctional Institution, becoming the first active major leaguers to serve jail time. The group was released from prison after serving only 90 days. Baseball commissioner Bowie Kuhn subsequently suspended all four for the entire 1984 season, but the suspensions were reduced after appeal and the four were allowed to return to their teams on May 15.

Lawrence Peter "Yogi" Berra (born May 12, 1925) is a former American Major League Baseball catcher, outfielder, and manager. He played almost his entire 19-year baseball career (1946–1965) for the New York Yankees. Berra was one of only four players to be named the Most Valuable Player of the American League three times and is one of only six managers to lead both American and National League teams to the World Series. As a player, coach, or manager, Berra appeared in 21 World Series. He was elected to the Baseball Hall of Fame in 1972.

Berra is widely regarded as one of the greatest catchers in baseball history. According to the win shares formula developed by sabermetrician Bill James, Berra is the greatest catcher of all time and the 52nd greatest non-pitching player in major-league history.

Berra, who quit school after the eighth grade, has a tendency toward malapropism and fracturing the English language. "It ain't over till it's over" is arguably his most famous example, often quoted. Simultaneously denying and confirming his reputation, Berra once stated, "I really didn't say everything I said."
