Is Poulan and Husqvarna the same company?

I've noticed that Poulan and Husqvarna seem to have some overlap in their product lines, especially in the realm of outdoor power equipment. Could you clarify for me if these two companies are indeed the same? It's a bit confusing as they seem to offer similar tools and machinery, yet they maintain distinct brand identities. If they're not the same, perhaps you could explain the relationship between them, if any? Are they affiliated, competitors, or simply two separate entities with a similar focus? I'd appreciate any clarity you could provide on this matter.
