Mobile Advertising Watch is a leading technology media property dedicated to covering the rapidly evolving world of mobile advertising, reviewing new solutions, giving reliable and actionable tips and breaking important technology news.

There’s a great race going on. It’s the race to get up to speed with mobile, the fastest-growing medium for connecting with consumers around the world.

But for many marketers and media buyers, the world of mobile is still “terra incognita.” Who to call? Where to turn for help? What companies really know what they’re doing out there? Who, in short, are the top dogs in their respective domains?

That’s why Mobile Marketing Watch and Mobile Advertising Watch recently teamed up to devise a comprehensive list of the major players and influencers who have critical expertise in the mobile landscape in 2015.

In 2015, this is necessary knowledge. Consider this: the global mobile advertising market is expected to hit two significant milestones as early as 2016, according to eMarketer. Mobile should not just reach, but surpass the $100 billion mark in spending. When that happens, mobile will represent at least 50 percent of all digital ad expenditure for the first time in history.

Yes, we’re at a turning point. Once upon a time, there were advertisers who said, “Who needs TV? Radio is working great for us!”

Mobile is that next great wave. The one that advertisers will have to ride — or be drowned by, frankly.

So what companies have the knowledge, the experience, and the creativity needed to help marketers, advertisers, and agencies master mobile? We constructed the infographic below based on a thorough review of firms that really know their stuff and have amassed impressive track records of accomplishment for their clients that prove it. A few things define them all: they’re driven, they’re creative, they’re committed — but most of all, they’ve got what we call “mobile moxie to the max.”

We could say it’s a dog-eat-dog world out there. But it’s actually a mobile-eats-everything world right now. The mobile ecosystem is both more diverse and more complex than many realize. There is a host of needs to be met and a pantheon of companies offering solutions. That’s why it’s vitally important to know what talent is available — and to choose partners and platforms wisely.

We hope this helps.
