In the space of three weeks, AOL, Fox Interactive Media and now Yahoo have shuffled top execs.

Yahoo last night restructured, ousting both Chief Operating Officer Dan Rosensweig and media group head Lloyd Braun. AOL several weeks ago replaced CEO and chairman Jonathan Miller with NBC vet Randy Falco. At Fox Interactive, president Ross Levinsohn resigned and was replaced with a cousin, Peter Levinsohn. Meanwhile, in a move that was less earth-shaking--but still of significance to online advertisers--MSN promoted Joanna Bradford to chief media officer.

It seems as if the only major online company that hasn't made major changes in the last month is Google--which is probably too busy absorbing YouTube and figuring out how to stave off lawsuits to worry right now about shuffling executives.

Google also appears to continue on its successful revenue streak--a state of affairs that obviously keeps Wall Street happy. The search company's stock price is up 11% so far this year. At Yahoo, by contrast, the stock has fallen around 34%.

But it's not as if online ad revenue isn't growing at other companies. Yahoo and AOL continue to report double-digit ad revenue growth--results that typically would be considered good news. Those companies don't match Google for revenue growth, but neither does the rest of corporate America.

On one level, it appears that Google's huge winning streak has created unrealistic expectations for the rest of the industry. At the same time, it also appears that some of the older online companies like Yahoo, MSN and AOL, which were built around professionally programmed content, are struggling to compete in a world where Web users want to create their own content, or at least watch/read content created by other consumers.
