Obama took over the airwaves Wednesday night, hitting most of the important audience groups. According to Nielsen (above), Obama's 30 minute 8pm infomercial which aired on CBS, FOX, NBC, Univision, BET, MSNBC, and TV One drew a combined 33.5 million viewers. His later taped appearance on The Daily Show registered another 3.6 million hard to reach young viewers, a record audience for the program.

Obama even tied into the 11pm local news and cable news broadcast, with many stations and networks cutting live to his first joint appearance with Bill Clinton. CNN video below.

McCain attempts to manage the same type of hard to reach audiences with a just announced appearance on Saturday Night Live this weekend.
