What commenters say

• YouTube's massive revenue from advertisements, over $31 billion in 2023, is likely sufficient to cover its costs, given historical precedents for ad-supported media.
• The cost of storing and streaming content is reduced at scale, and companies like Google can design and manufacture custom hardware to improve efficiency.
• Netflix has a different business model, with a focus on monetized content and a smaller library, which reduces its storage and caching costs compared to YouTube.
• YouTube's algorithm prioritizes popular content, which may be an unintended consequence of its caching strategy, and this can lead to a lack of diversity in recommended videos.
• The marginal costs of streaming decrease with immense scale, allowing companies like Google to provide high-quality services at a lower cost.
• Starting a new video streaming platform with an ad-supported model may not be feasible due to the high costs and competition from established players like YouTube.
• The quality of video encoding is not a major concern for YouTube due to its massive user base and network effects, which allow it to prioritize other factors like cost and efficiency.
• YouTube's synergy with AdWords infrastructure is a key factor in its profitability, which may give it an unfair advantage over competitors.
