I assume it has the same arrangement as CNBC had with dLife for a few years, where that company produced a show about living with diabetes that aired Sunday nights until the current regime came in to change around their Prime schedule and wanted the time for their own. dLife still airs on the web, so I assume like "Your Business" it maintained a diehard and loyal audience and dependable advertisers week to week, and Sunday mornings are basically MSNBC's time to try to not compete hard with NBC due to "Sunday Today" and "Meet the Press", thus "Your Business" and their most wonky news shows are geared to a niche, but loyal audience.
"Your Business" has certainly outlasted all of those lousy "pay-for-play" three-minute paid placement shows where companies had Terry Bradshaw or another old athlete promote a business that cable news was lousy with in the 2000's (my bank did one of those fluff-filled profiles with Bradshaw and it was a complete 'what are you doing with our deposits?!' moment).
