Reliance Communications

Ambani founded Reliance Infocomm (later Reliance Communications) to lead the group's information and communications push, then lost it in the 2005 family-split brokered by mother Kokilaben, under which telecom went to younger brother Anil. The 2016 launch of Reliance Jio marked Mukesh's return to the sector and, in effect, his reprising of the digital infrastructure thesis he had first sketched with Infocomm.

Most striking was the fraternal collision: Mukesh's Jio priced younger brother Anil's Reliance Communications out of the market and ultimately bought it out. Anil publicly framed the carnage as the wireless sector's natural consolidation, telling media that the industry 'is not for 10 players to enjoy — this is for two or three or four players to enjoy.'
