John Donovan, CEO of AT&T Communications, announced today his plans to retire effective October 1, 2019. Donovan has for the past two years led AT&T’s largest business unit, which services 100 million mobile, broadband and pay-TV customers in the U.S., as well as millions of business customers, including nearly all the Fortune 1000.

The news comes amid several big changes in that business unit itself, and more in the broader telecom industry.
