Quiznos has nearly vanished from the American sandwich business, a bad outcome for a chain that once looked like Subway's main rival.

• Customers drifted to Subway, which grew to 41,000 stores worldwide by 2014.
• Quiznos peaked around 2011 and filed for bankruptcy a few years later.
• Nineteen states now have no Quiznos at all, including New York.
• The survivors are scattered thin — California leads with about a dozen locations, followed by Nebraska, with a handful left in Texas and Florida.

Outlook: With only a few dozen stores spread across the country, the brand looks set to keep shrinking rather than stage a comeback.
