In the 90s, Boyz II Men was well on its way to becoming iconic. Twenty years, four Grammys, a handful of record-breaking hits and 60 million sold albums later, the trio formerly a quartet continues to perform and make new music. But, as Nathan Morris, Wanya Morris and Shawn Stockman tell Oprah: Where Are They Now?, even one of R&Bs most beloved groups can struggle in todays evolving entertainment industry.

One of the challenges of fame would be, I guess, staying famous, Wanya chuckles.

The initial slowdown after Boyz II Mens famed ascent was a bit of an awakening back in the day. We couldnt even forecast the actual success that wed have, hence not really recognizing the type of success that we had until things actually died down, Wanya points out.

The journey from then to now has been an adjustment for the singers.

One of the favorite lines is, You guys used to be my favorite group, Nathan says. Sometimes we ask ourselves, Well, what does used to be mean? Does that mean were not anymore?

Plenty has changed since Boyz II Mens Motownphilly days, and one of the biggest factors affecting musicians success comes down to pacing, according to Wanya.

Were in an instant-coffee-type society where things happen so fast, he says. Gone are the days of hard work into longevity. And talent! You know, its just so easy now to be famous.

The industry changes constantly, Shawn adds. Whats hot today aint hot today.

You can catch up with Boyz II Men on Oprah: Where Are They Now?, airing Saturday at 9 p.m. ET on OWN, or on demand via the Watch OWN app.
