Aren't all artificial pitches Astroturf?

Something I learnt the other day. Astroturf is a brand name for one make of artificial pitch. I learnt this when chatting to a leisure centre about their website. Their artificial pitches are not Astroturf ones and so cannot use the name Astroturf on their website. This will of course mean they loose out on hits to their website, loose out on bookings for their artificial pitches and thus loose money. Why, because so many people think Astroturf is just another name for an artificial pitch and will Google Astroturf when trying to find an artificial pitch to play on and so they might never discover their local leisure centres artificial pitches..
