3: ADVERTISING.

The global advertising industry will surpass $1 trillion (US $1 trillion, €953 billion) in total revenue this year for the first time in history, with a forecast of 7.7% growth to $1.1 trillion (€1.04 trillion) by 2025. The estimates come from GroupM, the media investment holding company of WPP, which points out that "the strong results of the world's largest advertising vendors and increased digital expansion have driven global advertising investment growth to 9.5% this year compared to the previous year." These figures exclude political advertising related to the recent US presidential campaign, so the total volume would have been much higher than reported, although no figures are available.
