Baidu's interesting appearence on CCTV

CCTV's Spring Festival Gala has been a must-see program for the Chinese people for the last 26 years. All the major companies try to place some sort of commercial tonight at CCTV, the sole TV station broadcasting this special event. It is like Super Bowel for the Americans. One of the major sponsors is Baidu tonight, not only because of its commercial appearance, but also its CEO Robin Li showed up in the front rows of guests and was under the flash light. This is interesting since Baidu was just under investigation by a CCTV's program less than a month ago. Baidu apologized for its wrong business conducting and its stock price responded negatively. So what does tonight imply? CCTV has stopped the investigation after it got huge chunk of money from Baidu? There must be some money deal behind the curtain. At least that is what my impression is after tonight. Should not CCTV avoid Baidu due to conflict of interests? Oh well, I guess not, because it is in China.
