Online advertising generated £13.4bn in the UK in 2018 (up 13% since 2017). This represents 57%  of total UK advertising revenue (television was the second largest sector at £5.1bn – 22% of total  advertising revenue).

Google and Facebook together generated an estimated 61% of UK online advertising revenue in  2018. Their websites are the most visited by adults in the UK, but their share of revenue is far  greater than time spent (35%).

Subscription is growing fast as a business model, particularly for entertainment and news where it  accounted for 64% and 39% of revenue globally.
