Yet there are some crucial ways in which Google differs from Microsoft．For a start，it is a far more innovative company，and its use of small，flexible teams has so far allowed it to remain innovative even as it has grown．Microsoft，in contrast，has stagnated as a result of its size and dominance．It is least innovative in the markets in which it faces the least competition—operating systems，office software and web browsers—though it is，curiously，still capable of innovating in markets in which it has strong rivals(notably video gaming)．
Try to avoid using Microsoft software for a day，particularly if you work in an office，and you will have difficulty；but surviving a day without Google is relatively easy．It has strong competitors in all the markets in which it operates：search，online advertising，mapping，software services，and so on．Large firms such as Yahoo，which previously farmed searches out to Google，have switched to other technologies．Google’s market share in search has fallen from a high of around 80％ to around 50％ today．Perhaps the clearest evidence that Google’s continued dominance is not inevitable is the fate of Alta Vista，the former top dog in Internet search．Who remembers it today?
