Hi, BrocksHarris and welcome to Wikipedia. I am an employee in Suddenlink's corporate communications department and monitoring our Wikipedia page is among my duties. While the changes you made are accurate, the earlier stated data is in keeping with how MSO size is usually described. Here's a souce you could link to to support those figures. http://www.sweetwaterreporter.com/content/suddenlink-launches-suddenlink2go-app . For the purpose of Wikipedia, I think stating how many customers we serve is more indicitive of who we are than how many we could potentially serve.
I'll be proposing the post revert to "7th largest" and 1.4 million customers descriptions. I'll leave the list of major states we serve. THanks.
