IBM not only still exists, they are massively successful. Today they're worth more than Microsoft, in fact, because of a strategic decision to refocus on selling to businesses that has worked out extremely well. They've stopped being a household name since they stopped selling to households, but I doubt they're losing much sleep over that.
Microsoft's ratio of popular to unpopular consumer products has been dismal for years; it's hardly unreasonable to think they might likewise do better by refocusing.
