45.4 million people watched at least one minute of the 2010 NFL Draft which took place last weekend..
ProFootballTalk reported this statistic in an article which can be viewed (here).
Last year, when the draft spawned over just two days, about 40 million viewers were drawn.
The feedback from the public has generally been positive regarding the new three-day format, and now with the numbers to back it up, there is a good chance it will be the new standard in how future Drafts will be held.
