Which reality series follows contestants competing to become the next top fashion model under the guidance of Tyra Banks?

The reality series in which contestants compete to become a top fashion model under Tyra Banks is 'America's Next Top Model'.

Contestants take part in photo shoots, runway challenges, interviews, and modeling assignments. A judging panel evaluates their performance, and one contestant is generally eliminated each episode. Tyra Banks created the program, served as its host, and was a major figure in its judging and mentoring structure.

The US series premiered on UPN in 2003 and later moved to The CW. It ran for 24 cycles, using the show's term for seasons. The format expanded into international versions under the 'Top Model' brand.

The show is often remembered for turning modeling into a reality-competition format accessible to a mass television audience. It combines professional fashion advice with elimination mechanics, so it differs from documentary series about established models or ordinary fashion casting programs.
