The company that has the world’s biggest market for ad tech is having a hard time.

Google has been the biggest spender on ads for years, but the company is still struggling to grow its revenue.

That’s due in part to its huge market share, which makes it the largest advertising platform in the world.

And while the growth in search has helped Google to become a dominant force in online advertising, it’s still not enough to make up for the lost advertising revenue it has already lost.

According to an article published Wednesday by CNBC, Twitter is in the midst of the worst ad crisis in its history.

In the past few years, the social media giant has spent more than $200 billion on advertising, more than any other company.

As of January, Twitter had lost about $1.5 billion in advertising revenue, which is a loss of $4 billion a day.

The ad industry has been struggling for years to make ends meet as it attempts to compete with the growing online ad market.

The company lost $7 billion in ad revenue in 2017 alone.

Twitter had a $2.5 trillion ad budget in 2017.

It is a problem that goes beyond the tech world, but it has hit home for investors as well.

When Google was still the biggest marketer of online advertising and Twitter was the largest, it had the ability to buy ad space on its own.

That gave the company a large chunk of the ad revenue it was spending on advertising.

That meant that Google could buy advertising space in the Google News ad network and Google’s YouTube video ad network, which have been the main sources of revenue for the company for years.

Now that the company has seen that revenue go up so much, it is having trouble paying the bills.

And when you’re paying for advertising on your own platform, it makes it hard to get your advertisers to spend money there.

This isn’t a good situation for investors.

The biggest stock in the company, Twitter shares, are up more than 15 percent since the article was published.

The stock fell by more than 5 percent on Wednesday morning.

“Twitter has lost billions of dollars in ad revenues,” said Josh Siegel, chief market analyst at Sohn.

“The company is in an extremely difficult position financially.

Its shares have dropped about 15 percent from their high of $180 in mid-December.”

Google’s problem isn’t just in the advertising space, Siegel said.

“If you look at the revenue stream, it would be in the billions of dollar range.

This is the biggest one-day loss we’ve ever seen on the company’s market capitalization,” he added.

As investors scramble to figure out what’s going on, the company hasn’t done anything to help the situation.

“This is an interesting point, because the biggest problem is not that Twitter is losing money, but rather that it’s unable to spend the money it already has,” said Siegel.

Google hasn’t released the details of the crisis it has created, but sources familiar with the situation told CNBC that Google’s ad revenue was down by more the $8 billion in 2017, which was more than the $2 billion it lost last year.

In 2018, Google’s revenue dropped to $2,726 billion from $3,892 billion in 2018.

As the company struggles to make payroll, its stock is expected to fall further.

Twitter also faces another problem.

“They are seeing some of the growth they have seen on Google and Twitter, which they have attributed to their growing search business,” said Jeffrey Yohannes, a research analyst at Sterne Agee.

“And this is a concern for Twitter.

The way it operates has been to use Twitter as an advertising platform to get its users to share content and give it to advertisers.”

“But there are people out there that are using Twitter to make money, which isn’t good for them,” he said.

Siegel believes that Twitter will continue to see its ad revenue decline and that it will be unable to pay for its advertising revenue to continue growing.

Twitter is the largest social media platform with more than 75 million users, according to the company.

The platform is popular with teens, millennials, and those with small businesses, and the company will need to keep growing its advertising platform if it wants to continue making money.

“It’s the biggest challenge they’ve had,” Siegel added.

“I think it’s going to be tough to make the numbers work, especially if they’re trying to grow by paying for ads and not advertising.”
