Todd Spangler NY Digital Editor Just over three years ago, Netflix unequivocally shot down the idea that it would ever roll out an ad-supported streaming service. “When you read speculation that we are moving into selling advertising, be confident that this is false,” the streamer said in its second-quarter 2019 investor letter. “We believe we will have a more valuable business in the long term by staying out of competing for ad revenue and instead entirely focusing on competing for viewer satisfaction.” Clearly, Netflix’s thinking about advertising has changed. Both Netflix and Disney+ are launching ad-based tiers this fall, seeking to broaden their addressable markets and tap into a new revenue stream as subscriber growth has slowed — in Netflix’s case, it lost 1.2 million in the first half of 2022, compared with a net gain of 5.5 million in the prior-year period.
