CTIA gives $235 billion for consumer mobile data revenue (CTIA only has a detailed summary for its 2025 report, which gives $224 billion for 2024, https://api.ctia.org/wp-content/uploads/2025/08/2025-CTIA-Su..., but second hand reports give $235 billion for 2025, e.g. https://www.lightreading.com/wireless/inflation-mostly-skipp...).
Video is a bit trickier to nail down since there isn't a single authoritative group putting out numbers, but most whitepapers converge around $150-200 billion (see e.g. https://www.prnewswire.com/news-releases/total-subscription-...).
I probably should've worded my reply better (eternal problem of mine). I wasn't doubting you so much as being amazed people spend so much.
Thank you for the detailed links though!
