sales (are doing something)

"Sales" are the number of items you sell or the amount of money you make from selling things:

Sales this quarter are strong.

Sales are down this month.

Sales can be "strong" or "weak", and they can:

  • increase
  • decrease
  • rise
  • fall
  • be up
  • be down

(something) is steadily (changing)

To "steadily increase" means to keep increasing by the same amount, again and again. Here's an example of some steadily increasing numbers:

20 > 25 > 30 > 36 > 41 > 45

Here are some numbers that are increasing, but not steadily:

20 > 29 > 27 > 28 > 40 > 40

Numbers can also steadily decrease or fall, which means to go down little by little.

(something) has been (doing something) (since a point in time)

This is how to talk about an action that started in the past, and is still happening now:

I've been taking kickboxing classes at my neighborhood gym.

Whenever you use the word "since", you have to use the perfect form "have done":

I've known him since he was born.

We've been ranked #1 every year since 1990.

You shouldn't use the simple past tense ("knew", "were") with "since".

a launch

When a rocket "launches", it shoots up into the air. But to "launch" a new product or business means to create it and release it to customers. When you're talking about this event, you call it "a launch".
