NEW YORK (TheStreet) -- Verizon Communications (VZ) - Get Reportdropped after reports emerged that Dish Network (DISH) - Get Report is in advanced talks to acquire T-Mobile U.S. (TMUS) - Get Report . Comcast (CMCSA) - Get Report edged lower after it reached a deal to acquire an advertising technology company Visible World. 

Verizon fell 1.8% to close at $47.25.

The telecom carrier took a hit after reports emerged that rival T-Mobile U.S. is in advanced talks to be acquired by Dish Network. 

Citigroup analyst Michael Rollins, according to a NEW YORK (TheStreet) --" target="_blank"> report in the Wall Street Journal, said Verizon stands the most to lose in such a merger. Rollins, in a report noted in the Journal, said, "A merger could quickly catapult Dish into the wireless arena and strengthen T-Mobile's distribution, product bundling capabilities, and network capacity."

Dish has a sizable treasure trove of specturm, or airwave, licenses. And although it hasn't put those airwaves to use for a wireless service, T-Mobile certainly can and it would allow it to jump over Verizon and AT&T T in terms of spectrum availability to the No. 2 spot.

Comcast slipped 0.45% to end the day at $58.69.

The cable company fell even though it agreed to buy Visible World, a tech-advertising firm. Visible World gleans data on users' zip codes from cable set-top boxes and other sources, then delivers targeted advertisements to certain audiences and households, according to a report in the Wall Street Journal

Comcast is currently an investor in Visible World, according to a MarketWatchreport. Terms of the acquisition were not disclosed.  The report also noted that should the buyout go through, Comcast would gain a larger position in the area of TV advertising that is driven by data information.
