Some data (with rounded numbers):
- 150,000 US professional photographers (BLS)
- 620,000 YouTube channels with 100k subs (Google)
- 6,600,000 ILCs shipped in 2024 (CIPA)
Extrapolate the US number to maybe 1,000,000 global professionals (big grain of salt, but the US represents ~25% of the population of the 'developed' world).
So if every professional photographer and every 'successful' YouTuber (as defined by a silver play button) bought a new ILC in 2024 (which didn't happen, of course), then that's about 25% of the market. So maybe the 'pro/creator' bucket accounts for 10% of the ILC market. Fully acknowledge there are many assumptions in the above, but even with those it's apparent that someone suggesting that professionals account for the majority camera sales is way off base.
The bottom line is that the market comprises a range of buyers, as Canon puts it they, "
...offer a lineup that satisfies both demand for still image photography from professional photographers and camera enthusiasts, and for diverse video recording from social media users."
