Bama Charlie seems like a good enough guy. Let's face it, any fan for a team as successful as his and still showing humility is a rarity in the Internet space.
OK so here's my attempt at revenue vs. income differentiation. You own a business. It's a football camp. Kids come to the football camp and you charge them $1,000 each to attend. 900 kids attend and they all pay. And none of their checks bounce! This is an imaginary example, it's true...
At any rate the total collection of all funds paid to you is $900k. That is revenue. Revenue is the total of all funds paid to your business.
But to run your business you also need to buy lunches for the kids, rent practice equipment and facilities and pay your coaches and instructors. Let's say that costs $800k. Those are your total expenses.
So your football camp was a success. You generated a profit of $100k. Sometimes people also call this figure "Net Revenue" although that is more typically used to describe subtotal figures (such as revenue minus cost of goods sold). But that source of confusion is why you'll often see journalists mix those figures around. Regardless, your profit in this case is $100k. Revenue - expenses = Profit.
Now it's the end of the year and it's time to pay taxes. The IRS looks at your business and says, you made $100k. That's reportable income. The IRS then uses a bunch of terms like adjusted gross income which involve modifications off that $100k. But the point is that you must report $100k, the profit from your football camp business as INCOME. If the football camp were a corporation, it would report $100k of pretax income which would then be subject to corporate taxes.
