Google doesn't celebrate the history of Writely or Android-pre-Google that much and Microsoft don't promote the history of Excel-pre-Microsoft that much either.

Their celebrations would be more like "10 years ago today we killed the only product of ours that you ever loved."

> Microsoft don't promote the history of Excel-pre-Microsoft that much either.

That’s probably because no such history exists, Excel was always a Microsoft product (even if they aren’t the inventors of spreadsheets).

They were probably thinking of PowerPoint, which did exist before Microsoft acquired it.

You’re right! PowerPoint. I stand corrected.

Sure but Apple does celebrate its products via Newsroom. Hell they even did it for iTunes in 2004
