Ecco

Ecco is a New York–based publishing imprint of HarperCollins. It was founded in 1971 by Daniel Halpern as an independent publishing company; Publishers Weekly described it as "one of America's best-known literary houses." In 1999, Ecco was acquired by HarperCollins, with Halpern remaining at the head. Since 2000, Ecco has published the yearly anthology The Best American Science Writing, edited by Jesse Cohen. In 2011, Ecco created two separate publishing lines, one "curated" by chef-author Anthony Bourdain and the other by novelist Dennis Lehane.

An imprint is a brand inside a larger publishing house, often with its own editors and list. Imprints of large groups usually acquire through literary agents; read recent titles to see whether your book fits the list, then target agents who sell to it.
