I have been tasked with developing a marketing plan for a college course. :)
Normally I would be able to find a lot of this information in company SEC filings and other places but there are a lot of manufacturers that are privately owned and do not release that type of data (i.e. Dyson). I do see from time to time that there will be a bit of information on percent of market share by a company but it is never all in one spot and not for all major (top 4 or 5) companies in the same year.
Several years ago, I assisted a college student with a similar task. Would be happy to do the same for you, if you like.
