Spin the globe in 2014 and you'll see positive signs for advertising across the planet. Ad spending finally is on track to increase in all regions, and the pace of global spending is picking up. Here are 10 points to keep in mind about the worldwide ad market.

Insights gleaned from a forecast that Publicis Groupe's ZenithOptimedia is releasing today:

Global ad spending is gaining momentum. Worldwide spending will rise a robust 5.3% in 2014 and 5.8% in 2015 and 2016, up from 3.6% in 2013. Put another way, the ad market next year will essentially match its pre-recession growth rate (5.4% in 2007).

Global spending is at an all-time high. Ad spending in 2013 will top $500 billion for the first time. That's $90 for each person living in the markets tracked by ZenithOptimedia.

U.S. spending remains below pre-recession levels. The U.S. won't pass its 2007 ad-spending peak (about $178 billion) until 2015. But U.S. ad growth is accelerating; ZenithOptimedia predicts a 4.7% increase in 2014, the fastest growth since 2004. It expects a 4.6% increase in 2015 and 4.1% in 2016.

Worldwide Ad Spending by Medium

All regions are rising. Latin America has been the fastest-growing region in ad spending since 2010 and will keep that lead position through 2016. Latin America growth will accelerate each year from 2013 (8.1%) through 2016 (12.7%). Spending in Asia Pacific will score solid single-digit gains in the range of 6% to 7% through 2016. Western Europe will see modest growth of 1.9% in 2014 and 2.3% in both 2015 and 2016 following declines in 2012 and 2013.

The internet is now the world's second-largest ad medium. It rocketed past newspapers in 2013 into the No. 2 spot, behind TV. As recently as 2005, the internet ranked sixth in global ad media, behind TV, newspapers, magazines, radio and outdoor. The internet in 2013 captured 20.6% of 2013 global ad spending (21.7% in the U.S.). In 2016, ZenithOptimedia expects the internet to account for 26.6% of global spending (30.7% in the U.S.).

China remains a hot spot. Ad spending grew and will keep growing in the range of 10% each year from 2012 through 2016. China is the No. 3 ad market (behind the U.S. and Japan) and in 2013 had the fastest growth among the world's 10 largest ad markets. The most China-centric advertisers among Ad Age's 100 Largest Global Marketers: fast-food seller Yum Brands (KFC), which placed 32.8% of its 2012 measured-media spending in China; energy-drink marketer Red Bull (27.5%); and watchmaker Swatch Group (24.1%).
