The speaker puts up the “Company background” as the first slide with bullet points full of founding dates, employee numbers, when the second office was opened, etc. etc.
You probably lost half your audience.
For the presenter, the company history is incredibly relevant. It summarises your entire path (10 years) that got you here neatly on 1 page. It makes total sense.
For the audience, company history does not matter that much (maybe with the exception of luxury brands), what solution are you offering today? Also, company history slides tend to look remarkably similar across companies. So the audience probably saw it before, somewhere else.
Often, the history slide is a left over from when the company was still small. It always was page 2 of the deck, we just updated the employee and office numbers for each presentation. And the same slides are probably used in different presentations. When the founder addresses the annual sales staff gathering, the company history told directly by her, might actually be funny and/or insightful. But she is unlikely to stick to the bullets on the slide. And, the same bullets in the hand of a sales rep sound boring and without context.
