The western genre is embedded in the history of television in America.
Western characters that became popular in the middle of the 20th century provided their audience with the impression of the American frontier, a land of adventure, lawlessness, and heroism.
Western television shows were prominent on television between the 1950s and 1970s. Classic television programs like Bonanza, The Lone Ranger, and Gunsmoke were popular with families across the country and, for the most part, created new standards for character development and episodic storytelling.
Western characters did not simply entertain, but carried along with them greater undercurrents of the culture: themes as justice, community, and the war between order and chaos. Viewers were intrigued by rough terrains and valiant men and women who prowled over them. The heroes that were not simple gun fighters, but lawmen, family, partners, and wanderers, whose stories appealed to an audience of all ages.
5 iconic western characters who made TV a frontier classic
1) Marshal Matt Dillon (Gunsmoke)

Marshal Matt Dillon is one of the most powerful Western characters. Played by James Arness, Dillon was the moral and legal guardian of the Kansas town, Dodge City, in the turbulent 1870s. He was a poster child of strength, determination, judgment, courage, and management.
Gunsmoke first started as a radio show in the year 1952 and transitioned to TV in the year 1955. People watched it over the 20 seasons and almost 635 episodes, becoming the longest-running prime-time Western in the history of the U.S.
2) The Lone Ranger & Tonto (The Lone Ranger)

The Lone Ranger (Clayton Moore) and his faithful companion Tonto (Jay Silverheels) were pioneers in the history of television with the first major crime-fighting western characters.
Since its premiere in 1949, The Lone Ranger followed their masked hero and his Native American companion through their process of restoring justice throughout the American West, sometimes aiding the weak as they fought the good fight. Their alliance broke all the stereotyped perceptions of the time and had a common front on either side of the race.
Within a short time, The Lone Ranger became the first massive success of the ABC network and the highest-rated series in the channel's history as it caught the hearts of both kids and adults. Its impact has not dwindled and has given birth to feature films and later tributes.
3) Bret Maverick (Maverick)

When Maverick first aired in 1957, James Garner subverted the Western hero type as Bret Maverick. Instead of a stoic or dangerous gunslinger, Maverick was a witty, comic poker player who employed guile, rather than confrontation, and never resorted to violence unless his conscience compelled him to do so.
The combination of action and fun in the show was special, and Maverick always found himself in trouble because of his enjoyment of gambling and pretty women, which offered much material that was comedy-related.
The performance not only made Garner a Hollywood leading man but also created an added charm and relatability to the western characters. Maverick outperformed other programs on the number of viewership, which contributed to its status as a classic Western.
4) Eric Hoss Cartwright (Bonanza)

Dan Blocker played the lovable lumbering giant, Eric Hoss Cartwright, a character on the long-running and perhaps best-known of the TV westerns, Bonanza. It debuted in 1959 and followed the exploits of a well-to-do family named Cartwright in Nevada. The show produced 14 seasons and more than 400 episodes.
Hoss managed to become a breakout character due to his profound sense of loyalty, good nature, and compassionate manner in which he treated his friends and family.
The exit of Hoss was historic, since the show did not replace him, which had never been the case with a star lead in TV. His everyman charisma and benign toughness imbued him with a sense of permanence in the family-driven Western storytelling.
5) Walt Longmire (Longmire)

Though classic western characters were a great success in the middle of the 20th century, Walt Longmire is the evolution of the genre.
Longmire, a small town Wyoming sheriff (played by Robert Taylor), is based on the popular eponymous novels by Craig Johnson. The show (2012-2017) offers great skill in mixing conventional Western values with modern sensibility, making Longmire a reserved, conscientious lawman, an agent of a bridge between the old and the new, and maintaining order in the community.
The influence of Longmire reveals the enduring strength and versatility of Western archetypes, highlighting their applicability in modern times while maintaining tradition.
All these characters contributed to the definition and popularization of the Western characters in TV, and this narrowed the genre to be an everlasting classic in American entertainment and culture.
