An average CPM is not a price

You spent $4,000 on streaming TV last month, and the report says your average CPM was $19.80. Here is a question that number cannot answer: what did the four thousand dollars buy?

Two campaigns, one average

Picture two campaigns that both report a $19.80 CPM.

The first bought evening impressions on sports and news channels, on TV sets, in the metros where your customers live. The second hit the same average a different way: a thin slice of $32 prime inventory to anchor the number, and a long tail of $8 overnight autoplay nobody watched. Same report line. Very different businesses.

That is the problem with an average: it is a summary of a distribution you are not allowed to see. Any mix of good and bad can be arranged to produce a defensible-looking number, and from the outside you cannot tell which mix you got. The average is not the price of anything. It is the price of everything, divided by a count.

What a receipt says instead

Antebyte keeps the full record of every impression it buys for you, and your impression log lists them one by one. A row looks like this:

Time	Jul 18, 8:42 PM
Channel	Tubi · crime drama
Device	Samsung smart TV
Location	Denver, CO
Billed price	$0.0169

One row is trivia. Two hundred thousand rows are an audit trail. They answer the questions the average hides: which apps and shows the money actually ran against, what share served to TV sets versus phones, which metros got the weight, and what each impression cost you. The sum of the billed prices reconciles to your invoice, so your finance team can check ad spend the way they check any other vendor — line items against a bill, not a summary against a feeling.

Why this matters on an ordinary Tuesday

The receipts earn their keep when something drifts. Cost per acquisition creeps up over two weeks: on an averages platform you get to guess, or pay someone to guess for you. With the log you read what changed — the mix shifted toward overnight hours, or a cheap app started taking more of the budget — and you correct the targeting instead of restarting the campaign and hoping.

They also settle claims. "Premium CTV" is a phrase; the show names in your log are a fact. If the inventory is what the sales page said, the rows will say so. If it is not, you will know by Thursday, not at the quarterly review.

Ask for the rows

None of this requires believing anything about Antebyte. That is the point of the design: the claim rides on records you can read, not on our description of them. Our rates are published, the log is in the dashboard from your first impression, and the invoice is the sum of its lines.

And if you buy media anywhere else, one suggestion: ask for the rows. Every platform has them — an ad server cannot function without knowing what it served, where, and for how much. Whether they will show you is a choice.

Create a campaign and read your own log by tomorrow.
