As part of a business restructure, Verizon is planning to phase out the Oath brand and bring its platforms and services under a new division called Verizon Media Group.
Oath's extensive portfolio currently includes Tumblr, Yahoo Sports and HuffPost. The brand was launched in 2017 following the $4.5bn merger of Yahoo and AOL
A now deleted tweet from a Huffington Post journalist showed an all-staff email circulated to Oath staff from chief executive Guru Gowrappan, which read: "I want to be clear that we will continue to have a portfolio of brands and products - and we will always lead with those."
He added: "Over time we will transition to use Verizon as our company name and Verizon Media Group as our business unit."
Gowrappan said more detail, including a "transition timeline" would be provided to staff "by the end of the year".
Oath owner, Verizon announced on Monday that it was to reorganise its business segments into consumer, business and Verizon Media Group/Oath. However, Gowrappan's email confirms that the the Oath brand will eventually be sunsetted just over 18 months since it launched.
The Drum has reached out to Oath for a statement – at the time of writing it had yet to reply.
