The advertising market, hit by a fall in consumer spending under lockdowns, is recovering from the coronavirus crisis as restrictions to curb Omicron-linked infections ease.
France's second-largest broadcaster posted full-year advertising revenue of 1.14 billion euros ($1.29 billion), up from 980.5 million euros a year earlier and slightly above the 1.11 billion euros which it recorded in 2019.
"Advertising activity is continuing on the right trajectory in early 2022", M6 said in a statement, while warning of an uncertain health situation and reduced visibility as a result of the forthcoming French presidential election.
M6, which is owned by Bertelsmann's RTL Group, said a proposed merger with leading French rival TF1 was on schedule.
On Friday TF1 reported a 14.2% rise in full-year advertising revenue as economic recovery helped boost spending.
