For years, R. Kelly had seemed untouchable.

Acquitted on charges of child pornography, accused of misconduct with underage girls, Mr. Kelly long remained embraced by the music industry. He toured widely, appearing at Grammy parties and making records with stars like Lady Gaga and Jay-Z.

But on Friday, Mr. Kelly — once one of the biggest and most influential stars in pop music — was dropped by his record company, RCA, in the music industry’s highest-profile casualty of the #MeToo era.

RCA’s agreement to part ways with Robert Kelly, confirmed by a person briefed on the move who declined to be identified because the deal was confidential, came after weeks of protests. A recent television documentary, “Surviving R. Kelly,” drew wide attention for its visceral testimonials by women who said that as underage girls they had been lured into sexual relationships with Mr. Kelly, and abused by him mentally and physically.

Yet as pressure had mounted on RCA — including from other artists on its roster — the company remained silent. The news of Mr. Kelly’s departure was first reported by Billboard, and RCA, a unit of Sony Music Entertainment, made no formal announcement; by Friday afternoon, Mr. Kelly had simply been scrubbed from the label’s website.
