Define profitable, it's extremely easy to build something that generates revenue.
The difficult part is to build something that provides enough revenue to support 1+ employees, office space, etc

So if I spent 100 hours making something and spent 5 hours a week maintaining it and it cost £500 a month to run, and the revenue was £501 a month, to me that's profitable.
Now obviously it's not profitable enough to keep it in its current state as 5 hours of my time is worth more than £1 but it is worth the time and money investment to make it bring in more revenue.
For some definition of "easy", I guess.
I'd say it shouldn't be terribly difficult to find audience enough to generate enough revenue to cover costs with even just ad revenue on even mediocre projects.
Though I should also point out that the word 'revenue' doesn't necessarily equal profit.
Are you having a hard time generating even the first penny? What's the niche? Who's the audience? What are the revenue strategies tried?
Basically everything I have built is because I found it interesting rather than trying to make money, so I'm not too bothered. However if it is so easy, where are all the "Hello World" tutorials for bringing in revenue?
