Anyone riding the T in Boston has seen the sea of Metros spread out in the hands of Boston commuters. Seventy percent of Metro readers are under 45 years old, making the Metro a powerful tool for reaching this coveted demo.

The world’s largest newspaper, with 17 million readers every weekday in 83 cities, Metro is designed for young professionals, half of whom don’t read a traditional newspaper. Metro Boston reaches nearly 250,000 people daily, primarily along public transit lines.
